What is the Difference Between Cerebrum and Cerebellum?

The cerebrum and cerebellum are two distinct areas of the brain with different functions and structures. Here are the key differences between them:

Cerebrum:

• Largest part of the brain, accounting for 85% of the brain's weight.
• Responsible for voluntary movement, intelligence, and memory.
• Comprised of two cerebral hemispheres, each consisting of four lobes: temporal, parietal, occipital, and frontal.
• Divided into two sections: the telencephalon (front part) and diencephalon (rear part).
• Controls and coordinates almost all functions necessary for life.

Cerebellum:

• Second-largest part of the brain, accounting for 10% of the brain's weight.
• Responsible for motor coordination, posture maintenance, and balance.
• Located in the hindbrain.
• Composed of two cerebellar hemispheres and a medial vermis.
• Contains three lobes (anterior, posterior, and flocculonodular).
• Controls precision, coordination, accuracy of timing, and posture.

In summary, the cerebrum is responsible for higher mental functions, voluntary movement, and memory, while the cerebellum focuses on motor coordination, posture, and balance. The cerebrum is the largest part of the brain, contributing nearly 80% of its total weight, whereas the cerebellum is the second-largest part of the brain and is responsible for coordinating physical movements and maintaining balance.

Comparative Table: Cerebrum vs Cerebellum

Here is a table summarizing the differences between the cerebrum and cerebellum:

The cerebrum is the largest part of the human brain, contributing nearly 80% of its total weight, and is responsible for voluntary movement, intelligence, and memory. The cerebellum, on the other hand, is the second-largest part of the brain and controls precision, coordination, accuracy of timing, and posture.
