What are the main functions of the cerebrum? -
./ ./ ./ ./ ./ ./ ./ ./
correct answer The cerebrum handles conscious thought,
./ ./ ./ ./ ./ ./ ./ ./
memory, language, and sensory processing.

essing).
,What is the role of the cerebellum? -
./ ./ ./ ./ ./ ./ ./
correct answer The cerebellum coordinates voluntary mov

What are the main functions of the brainstem? -
./ ./ ./ ./ ./ ./ ./ ./
correct answer The brainstem connects the brain to the spin
./ ./ ./ ./ ./ ./ ./ ./ ./ ./
al cord and controls vital functions such as heartbeat, blood

pressure, and respiration. ./ ./
What is the function of the thalamus? -
./ ./ ./ ./ ./ ./ ./
correct answer The thalamus is the major relay station for s

ensory inputs (except smell) and filters information to the c
./ ./ ./ ./ ./ ./ ./ ./ ./
erebral cortex. ./
What does the hypothalamus regulate? -
./ ./ ./ ./ ./
correct answer The hypothalamus regulates homeostasis, i

, What is the function of the pineal gland? -
./ ./ ./ ./ ./ ./ ./ ./
correct answer The pineal gland secretes melatonin, which
