The brain is the control center of the body. This lab will help you understand the different parts of the brain and their functions.
In the laboratory, we dissect sheep brains because their parts and structure are similar to the human brain. The virtual sheep brain dissection laboratory will mimic the activity we would do in lab and teach you the basics of brain anatomy.

Click on the lab and go through all of the sections. Please see the Module 4 Lab Study Objectives for all of the structures you are responsible for. You are not required to learn any markings in the virtual lab that are not on this list.
Activity 2: Identifying Major Brain Regions
The brain is divided into four major regions.
Identify the major regions (A-D) in the picture and complete the table by giving a brief description of each region’s function.
|2. Brainstem= Letter||3.|
|4. Diencephalon= Letter||5.|
|6. Cerebellum= Letter||7.|
|8. Cerebrum= Letter||9.|
Activity 3: Brainstem and Diencephalon Subdivisions
The brainstem and diencephalon each contain 3 subdivisions.
Give the function of each major regional subdivision and identify which major brain region each subdivision belongs to.
Activity 4: Parts of the Brainstem
Identify the parts of the brainstem (A-I). Each letter will only be used once.
22. Superior colliculus
24. Inferior colliculus
25. Medulla oblongata
26. Cerebral peduncle
27. Corpora quadrigemina
Activity 5: Parts of the Diencephalon
Identify the parts of the Diencephalon (A-I). Each letter will only be used once.
33. Corpus callosum
34. Pineal gland
36. Pituitary gland
37. Optic chiasm
Activity 6: Functional Areas of the Cerebral Cortex
The cerebrum is the largest region of the brain and the cerebral cortex is the main gray matter for thinking. Each area and sense in the body has a dedicated area of the cerebral cortex. Sensory areas receive input for perception, motor areas initiate movements, and associative areas are involved in complex integration; memory, emotion, reasoning, and judgment.
Complete the table by matching each area of the cerebral cortex with its function and give the name of the lobe of the cerebrum it is in.
|Cerebral Area||Letter (A-L)||Lobe|
|41. Primary somatosensory|
|42. Primary visual|
|43. Primary gustatory|
|44. Primary auditory|
|45. Primary motor|
|47. Somatosensory association|
|48. Visual association|
|49. Auditory association|
Activity 7: Cranial Nerves
Most of the head and shoulders are under the control of one of the 12 cranial nerves, including all of the special senses, somatic senses, and motor functions.
Match the cranial nerve with its description or number (A-L). Each letter will only be used once.
A. Equilibrium and hearing
B. Speech and swallowing
D. Taste from posterior tongue
F. Taste from anterior tongue
G. Number X
H. Face sensation and chewing
I. Head and shoulder movement
J. Movement of eyeball
K. Number III
L. Number VI
