PREFACE
This instructor’s manual is designed to assist those who are using the Laboratory Manual to Accompany Hole’s Human Anatomy and
Physiology, eleventh edition by Terry R. Martin. It describes the purpose of the laboratory manual and its special features, and
provides suggestions for presenting the laboratory exercises to students. The instructor’s manual also parallels the laboratory manual,
exercise by exercise, providing labels for unlabeled diagrams and answers to questions that appear in the laboratory reports. For some
exercises, special instructional suggestions that propose alternative procedures, laboratory equipment, or laboratory techniques are
provided.
Most of the illustrations and labels parallel the textbook very closely as requested by many of the users of the laboratory
manual. Many of the leader lines are arranged differently than the book, and several illustrations are different than the textbook. This
has been requested also by many of the users of the laboratory manual. I have attempted to reach a balance that will be beneficial for
all students and instructors.
vi
AN OVERVIEW
The Laboratory Manual to Accompany Hole’s Human Anatomy and Physiology, eleventh edition, was written to accompany the
textbook Hole’s Human Anatomy and Physiology, eleventh edition, by Shier, Butler, and Lewis. As in the case of the textbook, the
laboratory manual is planned for students pursuing careers in allied health fields who have minimal backgrounds in the physical and
biological sciences.
The manual contains sixty-four laboratory exercises that are closely integrated with the content of a textbook (three of these
exercises only appear in the text website). The exercises are designed to review and illustrate various anatomical and physiological
facts and principles presented in the textbook and to help students investigate some of these ideas in more detail.
The laboratory exercises include a variety of special features that are designed to stimulate student interest in the subject
matter, to involve students in the learning process, and to guide them through the planned experiences. These features include the
following:
Materials Needed. The laboratory materials listed are those that students require to complete the exercise and to perform the
demonstrations and learning extensions.
Safety. If the laboratory exercise requires special safety guidelines, this section is included. General safety guidelines also appear
inside the front cover.
Some institutions might have committees for reviewing labs using live animals, biohazards, and physiology experiments
performed on students. Be sure your labs conform to their guidelines. You might find the forms available in Appendixes 3 and 4
useful at your school.
Introduction. The introduction briefly describes the subject of the exercise or the ideas that will be investigated.
Purpose of the Exercise. The purpose provides a statement concerning the intent of the exercise—that is, what will be accomplished.
Learning Objectives. The learning objectives list in general terms what a student should be able to do after completing the exercise.
Procedure. The procedure provides a set of detailed instructions for accomplishing the planned laboratory activities. Usually these
instructions are presented in outline form so that a student can proceed through the exercise in stepwise fashion. Frequently, the
student is referred to particular sections of a textbook for necessary background information or for review of subject matter presented
in some previous part of the course.
The procedures include a wide variety of laboratory activities and, from time to time, direct the student to complete various
tasks in the laboratory reports.
Demonstrations. Demonstrations appear in separate boxes. They describe specimens, specialized laboratory equipment, or other
materials of interest that the instructor may want to display to enrich the student’s laboratory experience.
Learning Extensions. Learning extensions also appear in separate boxes. They are planned to encourage students to extend their
laboratory experiences. Some of these activities are open-ended in that they suggest how a student can plan an investigation or
experiment and carry it out after receiving approval from the laboratory instructor.
Illustrations. Diagrams are used as aids for reviewing subject matter. Other illustrations provide visual instructions for performing
steps in procedures or are used to identify parts of instruments or specimens. Micrographs often are included to help students identify
microscopic structures or to evaluate student understanding of tissues.
Some figures, such as those involving the skull, are presented so that they are suitable for coloring. You may want to have
your students use colored pencils to highlight various parts of these illustrations. This activity should enhance their ability to observe
the figures more carefully and help them locate and identify important anatomical features.
Laboratory Reports. Immediately following each exercise, there is a laboratory report to be completed by the student. These reports
include various types of review activities, spaces for sketches of microscopic objects, tables for recording observations and
experimental results, and questions dealing with the analysis of such data.
As a result of these laboratory exercises, students should develop a better understanding of the structural and functional
characteristics of their bodies. In addition, their skills in gathering information by observation and experimentation should increase.
vii
INSTRUCTIONAL APPROACHES
Exercise Selection
Although the laboratory manual contains sixty-four separate exercises, it may not be possible to include all of them in any one
program. However, because many of the exercises are relatively short and because the procedures of others are divided into sections,
an instructor can easily select those exercises or parts of exercises that best meet the needs of a particular class.
These exercises also vary in the quantities of equipment needed to complete them; if necessary, an instructor can make some
selection based upon the amount of laboratory equipment available for use by a class.
Animal Dissection
In the laboratory manual, the preserved cat is used as the major animal to be dissected. Detailed instructions for dissecting certain
organs, such as the sheep brain, sheep heart, pig kidney, and mammalian eye are also included.
A laboratory option is to obtain a cadaver as a demonstration specimen. If this is not possible, consider a field trip to a
location that has a prosected cadaver. A minimum of two viewings is recommended—one during muscle study and the other near the
end of the course.
The Use of Animals in Biology Education*
The National Association of Biology Teachers (NABT) believes that the study of organisms, including nonhuman animals, is essential
to the understanding of life on Earth. NABT recommends the prudent and responsible use of animals in the life science classroom.
NABT believes that biology teachers should foster a respect for life. Biology teachers also should teach about the interrelationship and
interdependency of all things.
Classroom experiences that involve nonhuman animals range from observation to dissection. NABT supports these
experiences so long as they are conducted within the long-established guidelines of proper care and use of animals, as developed by
the scientific and educational community.
As with any instructional activity, the use of nonhuman animals in the biology classroom must have sound educational
objectives. Any use of animals, whether for observation or dissection, must convey substantive knowledge of biology. NABT believes
that biology teachers are in the best position to make this determination for their students.
NABT acknowledges that no alternative can substitute for the actual experience of dissection or other use of animals and
urges teachers to be aware of the limitations of alternatives. When the teacher determines that the most effective means to meet the
objectives of the class do not require dissection, NABT accepts the use of alternatives to dissection including models and the various
forms of multimedia. The Association encourages teachers to be sensitive to substantive student objections to dissection and to
consider providing appropriate lessons for those students where necessary.
To implement this policy, NABT endorses and adopts the “Principle and Guidelines for the use of Animals in Precollege
Education” of the Institute of Laboratory Animals Resources (National Research Council). Copies of the “Principle and Guidelines”
may be obtained from the ILAR (2101 Constitution Avenue, NW, Washington DC 20418; 202-334-2590).
*Adopted by the Board of Directors in October 1995. This policy supersedes and replaces all previous NABT statements regarding
animals in biology education.
Background Information
The procedures of many exercises begin by suggesting that students review specific sections of the textbook. If the subject matter
involved in a particular exercise has been covered recently in lecture, the students may be able to accomplish such a review rather
quickly. On the other hand, if the material has not been presented previously, this part of a procedure may be used as a means of
introducing information needed to understand the ideas presented in the exercise.
When the procedure is used to introduce new material, an instructor may ask students to complete the first section before coming to
the laboratory. Following this, some portion of the laboratory time may be needed for class discussion of the new material.

SUGGESTED TIME SCHEDULE
Different instructional programs provide different lengths of time for laboratory preparations, work activities, and follow-up
discussions. Other factors that influence the time required for each exercise are the availability and variety of laboratory equipment
and materials. Consequently, it is difficult to make precise suggestions for the amounts of time that should be set aside for particular
laboratory exercises.
The suggested time schedule was prepared with these limitations in mind. The hours listed for each exercise indicate the
minimal time that probably will be needed for students who are acquainted with the subject matter of the exercise to complete the
laboratory work. Students who lack background information and who have to read various sections of the textbook before beginning
an exercises probably will require additional time. Similarly, students who are expected to complete the laboratory reports in class
may need more time.

1. The 7 assorted common liquids for the pH tests could include among the following: orange juice, lemon juice, milk, bottled
water, baking soda solution, aspirin solution, borax solution, ammonia, vinegar, antacid, liquid soap, cola, and diluted
catsup. Any beverage can be used, and any household product, even solids if they can be dissolved.
2.
The unknown compounds could include among the following: diluted milk, diluted corn syrup, chicken or beef broth,
diluted potato soup, diluted pudding, salad dressing, egg substitute, and diluted yogurt. It is very important to use some
numbering code to keep track of which unknown is which. The unknowns often look alike and are easily confused. The
students need to be instructed to take care not to contaminate their unknown. They need to be reminded to perform all tests,
as students often think if they get one positive result they can stop. Be aware that different brands of food products can
contain different ingredients. Inform the students when heating the samples using Benedict’s solution, if there is a protein
present it may denature or become solid, which should not be interpreted as a positive result.

CARE AND USE OF THE MICROSCOPE
Instructional Suggestions
1. To stimulate student interest in use of the microscope, you may want to have students prepare wet mounts of pond water and
observe the various forms of life present. A plankton net is a helpful device to concentrate pond organisms. Students can be
encouraged to bring samples of pond water to class in preparation for this experiment.
2.
You may want to provide students with prepared slides of major human organs to examine as a way of increasing their
experience with using the microscope.
3.
If oil-immersion objectives are available, you may want to provide students with prepared slides of various forms of bacteria
to observe using these objectives.

CELL STRUCTURE AND FUNCTION
Instructional Suggestions
1. Instead of preparing cheek cell slides, you may want to have students prepare slides of plant cells using Elodea leaves or
onion skin.
2. If live frogs are available, you may want to pith the frogs and have students prepare wet mounts using small samples of the
ciliated epithelium that lines the oral cavity. They also can prepare smears of frog blood and stain the cells with methylene
blue, and prepare wet mounts of sperm cells from the testes of the male frogs. You then might provide students with
prepared slides of human ciliated epithelium, blood, and sperm cells and have the students compare the frog cells with the
human cells.

Major Events Occurring
Growth, duplication of cell structures, and normal metabolism take place.
Nuclear envelope disappears; chromatin fibers condense, forming chromosomes (paired chromatids);
centrioles move to opposite sides of the cell.
Chromosomes align midway between centrioles.
Microtubules pull chromosomes toward centrioles.
Chromosomes elongate and become chromatin fibers; nuclear envelopes reappear.
Cell membrane constricts, dividing cell into new cells (daughter cells).

The spleen is composed of reticular connective tissue. This type of tissue contains only short, thin, collagenous fibers (reticular
fibers) that are widely scattered. The result is a delicate distribution of fibers among cells and a fluid ground substance. (Spleen
repair is almost impossible due to the short reticular fibers. A ruptured spleen is usually removed in surgery.)

Melanin granules are concentrated within some of the most superficial living cells of the body. Because melanin absorbs the
ultraviolet radiation of sunlight, minimal damaging wavelengths reach the living cells of the dermis. (Most of the melanin
granules are orientated on the superficial side of the nucleus that serve as a protective shield of the nucleus of the epidermal
cells.)

The clavicles brace the freely movable scapulae, helping to hold the shoulders in place. If an excessive lengthwise force occurs
on this structurally weak bone, as when a person breaks a fall with an outstretched rigid upper limb, it is likely to fracture.

LABORATORY EXERCISE 24
CAT DISSECTION: MUSCULATURE
Instructional Suggestions
1.
You may want to provide the students with preserved cats that have been preskinned. Such cats are available from various
biological supply companies. The use of preskinned cats will save about an hour of class time and avoid the unpleasantness
that some students associate with the skinning procedure.
2.
You may want to reduce the amount of time spent in dissecting the cat muscles by having the students dissect only selected
areas of the cat. For example, you might have them complete Procedure D (muscles of the thorax), Procedure E (muscles of
the abdominal wall), Procedure F (muscles of the shoulder and back), and Procedure H (muscles of the hip and hind limb),
omitting the other sections.

Gastrocnemius, soleus, and flexor digitorium longus
The quadriceps femoris is stretched, stimulating stretch receptors (muscle spindles) within the muscle. As a result, impulses
pass along sensory neurons into the spinal cord and synapse with a motor neuron. Motor impulses travel out of the cord on
nerve fibers that lead to the quadriceps femoris. Muscle fibers contract, and the leg is extended at the knee joint.
Critical Thinking Application Answers
All of these reflexes are rapid, subconscious responses to physical stimuli.

LABORATORY EXERCISE 29
DISSECTION OF THE SHEEP BRAIN
Instructional Suggestion
Rather than have students dissect sheep brains, you might want to provide the class with samples of whole sheep brains and
sectioned brains for examination. This should extend the use of the available specimens.
Laboratory Report Answers
PART A
1. The human cerebral hemispheres are relatively
5.
larger than those of the sheep.
2. There are more convolutions and sulci in the
6.
human cerebrum.
3. The human cerebrum with its larger size and
7.
greater number of convolutions is more complex
and thus able to carry on more complex functions.
4. The human cerebellum is divided in the midline (vermis)
into two hemispheres, whereas the sheep cerebellum is
not divided.
The olfactory bulbs of the sheep brain are larger than those of
the human brain.
The olfactory, optic, and trigeminal nerves seem to be most
highly developed in the sheep brain.
The senses of smell and sight and the sensory functions
associated with the trigeminal nerve are highly developed.
Critical Thinking Application Answers
PART B
1-6. Answers will vary. The sheep brain and the human brain features are more similar than different. Therefore a complete list
of similar features would be very long. Among similar features include two cerebral hemispheres, medulla oblongata, pineal
gland, midbrain, thalamus, hypothalamus, pons, olfactory bulb, four ventricles, and others. (Note only 6 answers are
needed.) Mammal brains have more similarities than differences.

VISUAL TESTS AND DEMONSTRATIONS
Critical Thinking Application Answers
When using both eyes for observations, if the image of a small object falls on the optic disc of one eye, the object is still seen by
the other eye. This can be confirmed because the blind-spot demonstration will not work with both eyes open.

vision.
b. A person with 20/10 vision can see fro 20 feet what the normal eye sees from 10 feet. This person has better than normal
vision.
c. Astigmatism results in blurred vision because some parts of the image on the retina are in focus, while other parts are not
in focus.
d. The elastic quality of the lens tends to decrease with age.
e. The retina is lacking cones that are sensitive to red or green wave lengths (an X-linked/sex-linked trait).
PART B

2. The optic disc lacks receptors (rods and cones) and thus creates a blind spot in the retina.
3. The photopupillary reflex involves the construction of the pupil in response to exposure to bright light.
4. The photopupillary reflex occurs in both eyes even when one eye is shielded from the light; however, the shielded eye may
not show as much change as the exposed one.
5. When an eye is focused on a close object, the pupil constricts.
6. When the eyes are focused on a close object, they converge toward the midline.

ENDOCRINE HISTOLOGY AND DIABETIC PHYSIOLOGY
Instructional Suggestions
1. The responses and recovery to insulin shock work faster if the fish selected is very small (total length about 1”). The species
of fish selected does not seem significant so try a fish species that is readily available.
2. HumulinR administered in 200 units usually will suffice to induce insulin shock within about 5 minutes. If the responses are
too slow, try an increase to 400 units. Consult with your local pharmacist or veterinarian to purchase insulin.
3. If the recovery from insulin shock is too prolonged using a 10% glucose solution, try a 20% glucose solution.

3. (experimental results)
Recovery from insulin shock usually occurs within about 5-10 minutes.
Critical Thinking Application Answers
The main hormone regulating blood sugar is insulin. A normal person’s insulin level will adjust the blood sugar homeostasis
level according to changes in daily diets and exercise levels. A person with type 1 diabetes needs to attempt to have similar daily
diets and exercise to correlate with the designated daily insulin administered.

HEART STRUCTURE
Instructional Suggestions
1. You may want to have the students use colored

pencils to color the features of the heart and blood
vessels in figure 40.3. This activity should help them
observe the illustrations more carefully and locate the 4.
various features shown from different views in the
figures. They can check their work by referring to the
corresponding figures in the textbook, which are
presented in full color.
2. Instead of using preserved sheep hearts, you might
want to provide fresh pig hearts for dissection.
To reduce the cost of specimens used, you might provide
predissected, preserved sheep hearts for observation and
save the specimens for use with other classes.
Fresh beef hearts are sometimes available from meat-packing
houses. You might want to demonstrate the dissection of this
large heart. Try to make sure that the atria and large blood
vessels are left attached for this purpose.

right atrium and the right ventricle.
3. The chordae tendineae and papillary muscles prevent the
cusps of the tricuspid and mitral (bicuspid) valves from
swinging into the atria when the ventricles contract.
The thicker wall of the aorta allows it to withstand the
higher pressure of the blood pumped out from the left
ventricle. The thinner wall of the pulmonary trunk (artery)
is related to the lower pressure of the blood that leaves the
right ventricle.

The thicker wall of the left ventricle allows it to contract with greater force and create the high pressure needed to move blood to
all parts of the body (systemic circuit) except the lungs. The thinner wall of the right ventricle creates the lower pressure needed
to move blood a relatively short distance to the lungs (pulmonary circuit).

If live frogs are not available for the microscopic observation of blood vessels, you might want to provide small goldfish. The
head of a fish can be wrapped loosely in wet cotton to keep its gills moist, and the fish can be placed on a glass plate on the stage
of a microscope. If its tail is spread out beneath the microscope slide, the blood vessels can be observed with low- and highpower magnification. However, if the fish is not returned to water within a few minutes, it will likely die.

The tunica interna and tunica externa are similar in the artery
and vein. The tunica media of the artery contains relatively
greater amounts of smooth muscle and elastic tissue than that of
the vein.
Critical Thinking Application Answers
Because arteries are under higher pressure than veins, the thicker arterial walls help to maintain the strength and elasticity
necessary against their walls.
PART C
1. The blood in an arteriole moves with a pulsating

rapid flow, whereas that in a venule moves with a
steady slower flow.

2. A capillary could be identified by its small diameter
and the presence of blood cells moving in single file.
Blood moves fastest in arterioles, somewhat slower in venules,
and slowest in capillaries.
If noted, the flow from an arteriole into a capillary will change
from continuous flow to an interrupted flow and may cease flow
for brief periods of time. This irregular flow into the capillary is
a result of changes caused by the precapillary sphincter.

3.
The room environment should have a moderate temperature and be quiet (no talking).
The client needs to be relaxed and comfortable. A temporary increase in blood pressure could exist from smoking, pain,
anxiety, or a full urinary bladder.
Palpate the pulse first so that you are certain to pump the cuff high enough to not miss the first tapping sound. It also assures
that you do not pump the cuff so high that we alter the blood pressure when releasing air.

LABORATORY EXERCISE 45
CAT DISSECTION: CARDIOVASCULAR SYSTEM
Laboratory Report Answers
PART A
1. The parietal pericardium forms a relatively thick, tough sac that encloses the heart. It is attached to the large blood vessels at
the base of the heart and to the diaphragm.
2. The walls of the atria are much thinner than those of the ventricles. The wall of the left ventricle is much thicker than that of
the right ventricle.
3. Wall thickness is related to the force of its contraction and the amount of pressure it imparts to the blood inside a heart
chamber. The left ventricle has the thickest wall, contracts with the greatest force, and creates the greatest amount of blood
pressure in the heart chambers. The left ventricle is the pump for the systemic circuit.
4. In the human, the right common carotid artery branches from the brachiocephalic artery, whereas the left common carotid
artery comes directly from the aortic arch. In the cat, both common carotid arteries branch from the brachiocephalic artery.
5. In the human, the aorta divides to form the two common iliac arteries, which in turn give rise to external and internal iliac
arteries. In the cat, the aorta divides to form the external iliac arteries, and the internal iliac arteries branch from the aorta
independently.
PART B
1. In the human, the brachiocephalic vein is formed by the union of the internal jugular and the subclavian vein on each side. In
the cat, the brachiocephalic vein is formed by the union of the external jugular and the subclavian vein on each side.
2
In the human, the internal jugular vein is somewhat larger than the external jugular vein. In the cat, the external jugular vein
is larger.

LABORATORY EXERCISE 49
ACTION OF A DIGESTIVE ENZYME
Instructional Suggestion
For this experiment to work, it is very important to obtain amylase that is free of sugar. Some of the amylase sold by laboratory
suppliers in 2005 contained sugar, as can be determined by the control in tube 1 of this experiment. Ward’s Natural Science does
handle amylase (alpha amylase from Bacillus subtilis; catalog #944W4602) that is free of sugar, and several other companies
plan to add this product to their catalogs. If in doubt, call the supply company and consult with a person in technical support.
Keep any of the unused amylase frozen.

(98.6ºF).
b. The tubes in which digestion failed to occur could be placed in the 37ºC (98.6ºF) water bath. If digestion occurred at this
temperature, the enzyme was not destroyed by the previous treatment.
Critical Thinking Application Answer
The test would show a positive result for sugar. The experiment would not be valid as it would not show a change from starch to
sugar when sugar is already present. (Note: some amylase sold is contaminated with sugar.)

3. The tracheal rings are incomplete as they are in the human.
4. The structure of the primary bronchi and the trachea are similar.
5. The cat has three main lobes in each lung (anterior, middle, and posterior). The posterior lobe on the right side has an
accessory lobe associated with it, making a total of four lobes on the right lung. The human has three lobes in the right lung
and two in the left.
6. The diaphragm is attached to the lower rim of the thorax and to a central tendon.

d. Exercise causes an increase in the breathing rate. This is due in part to the joint reflex and in part to an increasing
concentration of blood carbon dioxide.
3. a. It is difficult for a person to breathe normally while thinking about it.
b. Depth of breath can be measured by breathing into an instrument that measures air volumes.
Critical Thinking Application Answer
A person who has hyperventilated may lose consciousness under water because of changes in the blood carbon dioxide and
oxygen levels causing respiratory alkalosis. This is accompanied by arteriole vasoconstriction to the brain, which deprives the
brain tissue of oxygen. Hyperventilation has a minimal influence on oxygen carrying capacity on the hemoglobin which is
normally nearly saturated (about 97.5%) in lung capillaries. However, hyperventilation can decrease the carbon dioxide enough
during breath-holding that depleted oxygen to the brain could cause unconsciousness. This loss of consciousness could occur
before the urge to take the next breath takes place.

1. The glans of the cat has small spines on its surface, whereas that of the human does not.
2. In the cat, the prostate gland is relatively small and is located some distance from the urinary bladder (it does not surround
the urethra). In the human, the prostate gland is relatively larger and surrounds the urethra near the base of the bladder.
3. The seminal vesicles are lacking in the cat.
4. The prepuce of the cat encloses the entire penis for protection. In the human, the prepuce or foreskin is vestigial and only
covers the glans of the penis. A circumcision is commonly performed on humans to remove the prepuce for sanitation and
other reasons.

increases as calcium ions help initiate muscle
contractions. There is danger of prolonged contraction.
Normally the rate and force of contractions decrease by altering
the usual polarized state of cardiac muscle cells. Excessive
potassium ions may result in cardiac arrest.
Critical Thinking Application Answer
This will allow the ionization to occur providing K+ and Ca++ when in a solution of water.
