Which side of the body does each cerebral hemisphere serve?

Each hemisphere serves the opposite side of the body, because the nerve fibres cross over in the brain stem.

What is the main function of the cerebellum?

The cerebellum coordinates balance, posture and muscle tone, and makes voluntary movement smooth and accurate.

Explain why the cerebellum is not said to initiate movement.

The instruction to move comes from the motor areas of the cerebrum, and the cerebellum only refines that instruction so the movement is properly timed and coordinated.

From where does the cerebellum obtain the information it needs?

It receives information from the balance organs of the inner ear, from proprioceptors in the muscles and joints, and from the eyes.

1
What is the overall function of the cerebrum?
Model answer
The cerebrum receives and interprets sensory information, compares it with stored experience and initiates the voluntary responses that follow.
2
Name four higher functions that depend on the cerebrum.
Model answer
The cerebrum is responsible for reasoning, memory, emotion and personality, and language.
