Study Notes
Cerebellum Location and Structure
- The cerebellum is located behind the brain stem and below the cerebrum.
- It is divided into hemispheres: the left cerebellar hemisphere and the right cerebellar hemisphere.
Cerebellum Function
- The cerebellum coordinates movement.
- It smooths out movements and makes them more accurate.
- It plays a big role in accuracy and finger movement when trying to touch something.
Information Flow in the Cerebellum
- The cerebellum receives information about the motor plan.
- The motor plan involves which muscles need to contract and at what intensity and duration.
- The cerebellum receives position sense information.
- Position sense information is not reaching consciousness and is used to compare the motor plan to the movement that's actually occurring.
- The cerebellum sends feedback back to the motor areas of the cerebrum to correct the movement.
Cerebellum Pathways
- Upper motor neurons in the cerebrum send axons down through the brain stem and cross over to talk to lower motor neurons.
- Lower motor neurons send information to muscles to make movements happen.
- Information about the motor plan is sent to the cerebellum through a separate pathway.
Cerebellum Coordination
- The middle part of the cerebellum coordinates movements involving the middle of the body (e.g., walking).
- The part of the cerebellum on the side is more involved in coordinating movements of the limbs.
- Different parts of the cerebellum coordinate movements involved in speech and moving the eyes.
Cerebellum Importance
- If the cerebellum isn't functioning properly, it can cause trouble coordinating movements and trouble enunciating.
- The cerebellum is essential for smooth and accurate movements.
Cerebellum Location and Structure
- Located behind the brain stem and below the cerebrum, the cerebellum is divided into two hemispheres: left and right.
Cerebellum Function
- Coordinates movement, making it smoother and more accurate.
- Plays a crucial role in finger movement and accuracy when trying to touch something.
Information Flow in the Cerebellum
- Receives information about the motor plan, including which muscles need to contract and at what intensity and duration.
- Receives position sense information, which is not conscious and is used to compare the motor plan to the actual movement.
- Sends feedback to the motor areas of the cerebrum to correct the movement.

Cerebellum Coordination
- The middle part of the cerebellum coordinates movements involving the middle of the body, such as walking.
- The lateral part of the cerebellum coordinates movements of the limbs.
- Different parts of the cerebellum coordinate movements involved in speech and eye movements.
Cerebellum Importance
- Essential for smooth and accurate movements.
- If the cerebellum is not functioning properly, it can cause trouble coordinating movements and enunciating speech.
