What do large cells do to reach their nutrient requirements? What does this do?

What is gray matter used for? White matter?

The large upper region of the brain

Involved in the control of muscles and the integration of information from other parts of brain + allows critical thinking to occur

Recieves sensory information from skin and skeletal muscles and is associated with the sense of taste

Receives information from eyes/associated with visual processing

Receives information from ears and is associated with auditory processing/involved in memory and speech

Helps maintain balance and posture of the body; motor area of the brain

Extends downward from the brain and connects to the spinal cord; controls basic life functions like heartbeat and breathing

Sensory relay station; receives impulses from most sensory neurons entering the brain and directs them to parts of the cortex to be interpreted

Controls hunger, thirst, temperature maintenance, water balance, blood pressure, and release of many hormones

A short segment of the brainstem between the cerebrum and the pons- particularily involved in sight and hearing- contains auditory and visual reflex arcs
