Introduction

The brain is the control center of the body. This lab will help you understand the different parts of the brain and their functions.

.

 

Activity 1: Virtual Sheep Brain Dissection

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.

Region (A-D) 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.

 

Subdivision Function Brain Region
Epithalamus 10. 11.
Medulla Oblongata 12. 13.
Midbrain 14. 15.
Hypothalamus 16. 17.
Pons 18. 19.
Thalamus 20. 21.

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.
