Briefly describe the structure of the cerebellum in human brain and mention its functions .
Answer
Cerebellum is much smaller compared to Cerebrum and is located under the cerebrum. Its function is to balance the body and coordinate muscular activities. The cerebrum decides an action, whereas the cerebellum implements the action. For example, if we get an idea to stand up and walk, it arises in the cerebrum, but the muscles involved in this process contract or relax under the control of the cerebellum.
