GUMMI BEAR LAB
PRELAB INSTRUCTIONS:
A. Use your notes, textbook, or other source to define or describe the following terms:
1) Frontal (coronal) plane –
2) Midsagittal plane –
3) Parasagittal plane –
4) Transverse (horizontal) plane –
B. Use your notes, textbook, or other source to describe and distinguish among the following anatomical
directions. Provide an example sentence for each. Make sure your examples are different from the ones
provided in your textbook or on the Anatomical Directions handout.
1) Cranial –
2) Caudal –
3) Superior –
4) Inferior –
5) Anterior –
6) Posterior –
7) Lateral (right & left) –
8) Medial –

LAB INSTRUCTIONS:
READ ALL DIRECTIONS CAREFULLY BEFORE PROCEEDING WITH THE LAB.
This is a group lab: students will work in groups of 2 – 4 as directed by the instructor.
However, individual students are responsible for knowing the anatomical planes & anatomical directions
presented in the lab.
Caution: razor blades are sharp & can cause injury if handled improperly.
(1) Obtain 1 lab sheet of construction paper, 1 scotch tape dispenser, 1 small paper plate, 1 razor
blade, & 10 Gummi Bear candies from the front lab counter.
(2) Using the razor blade as a scalpel & the paper plate as a cutting surface, carefully section 4 of
the Gummi Bears using these anatomical planes: (1) frontal; (2) midsagittal; (3) parasagittal;
(4) transverse.
(3) Scotch-tape the sectioned Gummi Bears to a section of the lab sheet clearly labeled with the
appropriate sectional plane. Gummi Bears should be taped “face forward” (anatomical position)
except for the back section of the frontally sectioned bear. Also tape a whole (unsectioned)
Gummi Bear “face forward” to the paper. Remember, neatness & the “stability” of the taped
Gummi Bears count!
(4) Use an ink pen to label (with arrows) anatomical directions on the sectioned Gummi Bears.
Use the following formula:
1) Frontal plane sections: anterior & posterior
2) Midsagittal plane sections: right & left
3) Parasagittal plane sections: lateral & medial
4) Transverse plane sections: superior & inferior
(5) Use an ink pen to label (with arrows) the unsectioned Gummi Bear to show the cranial
(cephalad) & caudal (caudad) directions.
(6) Make sure that all the members of your lab group are listed at the top of the lab sheet under
your group designation (Group A, Group B, etc). Return the completed lab sheets to the
appropriate area of the lab counter.
(7) Although eating is not usually allowed in class, you may reward yourself by eating whatever
remains of your group’s Gummi Bears. Enjoy!
(8) Clean-up: Return your tape dispenser to the front lab counter. Place your used razor blade
into the hot water bowl in the front sink or dispose of it as directed. Throw the paper plates into
the garbage can.

& spinal cord.
The navel is on the ventral surface of the
body.
The shoulders are superior to the hips.
The stomach is inferior to the heart.
The neck is cranial to the chest.

The knee is proximal to the ankle.
The knee is distal to the hip.
A visceral membrane covers the heart.
A parietal membrane lines the inside of
the body cavity.
The thighbone is deep to the surrounding
skeletal muscles.
The skin is superficial to the skeletal
muscles.
The medullary region of the kidney
contains the renal pyramids.
The cortical region of the brain contains
most of the association neurons.
* In the human body, dorsal & ventral are equivalent to posterior & anterior, respectively.
+
Cranial & caudal are used for structures of the torso & head.
** Proximal & distal are used to describe locations in the limbs or along a body tract.
++ Visceral & parietal describe structures found within a body cavity.
