BIO105 - Midterm Lab Practical - Study Guide
Please note that you are responsible for all the labs we did in class, as well as the notes
given. This study guide is a list of topics and material that are most likely to appear on the
midterm. The midterm will cover labs 1 – 6.
Histology:
 Be able to identify the histology sections we viewed in class:
simple squamous, simple cuboidal, stratified squamous epithelium; dense, regular connective,
adipose, hyaline cartilage, neuromuscular junction, neurons and neuroglia.
 Slides are posted on Chris Pickens’ website: www2.sunysuffolk.edu/pickenc. On the
exam, you will be asked to identify slides with a microscope. You should also be able
to list a location of each type of tissue.
The Microscope:
 Be able to label the parts of the microscope.
 What magnifications are scanning, high, and low power? What do the oculars add to
magnification?
 When should you use the fine focus? Coarse focus?
General Anatomy:

Know your directional terms: anterior, posterior, dorsal, ventral, medial, lateral,
proximal, distal, superior, inferior

Know your anatomical position and anatomical planes: coronal, sagittal, transverse

Recognize and apply the following movements: flexion, extension, abduction, adduction,
medial and lateral rotation, circumduction, dorsiflexion and plantar flexion.

Describe the 4 quadrants of the abdominal cavity. What major organs do they contain?

Identify the dorsal, ventral, cranial, thoracic, abdominal and pelvic cavities of the body.
Biomolecules and Tonicity:

What are the simplest forms of protein, carbohydrate, and lipid molecules?

Which lab tests did we do to test biomolecules?

Which types of chemical bonds exist in the macromolecules (proteins, nucleic acids,
triglycerides, carbohydrates)?

What is diffusion? Osmosis? What size molecules are capable of diffusion through a
membrane?

Explain what it means for a cell to be in a hypertonic, hypotonic or isotonic condition.
How will a cell in these conditions react?
The Musculoskeletal system:
What is the origin? What is the insertion?
Bones: Be able to identify on a diagram or model
Cranial, occipital, sphenoid, temporal, parietal, maxilla, mandible, cervical vertebrae, thoracic
vertebrae, lumbar vertebrae, sacrum, coccyx, true ribs, false ribs, floating ribs, sternum, clavicle,
humerus, radius, ulna, carpals, metacarpals, phalanges, coxa, femur, patella, tibia, fibula, tarsals,
metatarsals.
Muscles: Be able to identify on a diagram or model. Also, what function do they perform?
Frontalis, temporalis, obicularis oris, orbicularis oculi, trapezius, masseter, sternocleidomastoid,
abdominal muscles, serratus anterior, deltoid, pectoralis major, latissimus dorsi, biceps brachii,
triceps brachii, gluteus maximus, quadriceps femoris, hamstring group, adductor muscle group,
gastrocnemius, tibialis anterior.
Lab tests: When do we use these tests? How are their results interpreted?
IKI test
Benedict’s test
Biuret test
**Remember, this is a practical, you may be asked to interpret experimental results similar
to those we’ve gotten in class. The exam will consist of 25 stations with 2 questions at each
station (50 questions total; 2 points each). You will have 2 minutes at each station and 10
minutes at the end of the practical to revisit stations you would like a second look at. Bring
a pen/pencil and a calculator.
