Tutorial

What's Covered

Welcome to today’s lesson on the cerebellum. Today, you are going to be learning about the role of the cerebellum and how to identify its location in the brain. Specifically, you will look at:

  1. The Cerebellum’s Role
  2. The Cerebellum’s Location

1. The Cerebellum’s Role

The main role of the cerebellum is to coordinate voluntary movements. The cerebellum also has a role in coordinating motor activities, spatial awareness, timing, and planning. It is responsible for providing the timing needed for smooth, coordinated movements.

Term to Know

  • Cerebellum
  • A region of the hindbrain primarily responsible for coordinating voluntary movements.  
IN CONTEXT
The cerebellum plays a key role in field sobriety tests because alcohol has a direct effect on the cerebellum. Somebody who gets pulled over by a police officer and has to take a field sobriety test-- the police officer is actually measuring their cerebellar functions. The cerebellum is the part of the brain that controls your voluntary or your motor movements, so a person who is under the influence has inhibited coordination. 

2. The Cerebellum’s Location

The cerebellum is a part of the brain that's located in the hindbrain. If you are familiar with the different regions of the brain, you may know that the brain has a hindbrain, a forebrain, and a midbrain. The cerebellum is a part of the brain located in the hindbrain, and it is the largest region of the hindbrain.

Take a look at a diagram of the brain below to help identify exactly where the cerebellum is.



You can see the cerebellum identified in green in the image above. You'll notice it's quite a large region of the hindbrain. Your midbrain is the small area, your forebrain is the large area, and your hindbrain is located down at the bottom. You can see that the cerebellum is a large area in the hindbrain.



Summary

This lesson has been an overview on the functions of the cerebellum, which coordinate voluntary movements. You also learned how to locate the cerebellum in the brain, the largest region in the hindbrain.

Keep up the learning and have a great day!
