Study Notes
Brain Structure and Functions
- The cerebrum constitutes 80% of the total brain weight.
- The outer layer of the cerebrum is called the cerebral cortex.

- The cerebellum is NOT included in the forebrain.
- The cerebellum is involved in the coordination of voluntary movements and balance.
- The vestibular system in the inner ear, along with the cerebellum, is responsible for the balance of the body.
- The thalamus plays a role in transmitting sensory information to the cerebral cortex.
- The thalamus functions as a relay station for sensory information.
Brain Components and Functions
