They convert external stimuli from the organism's environment into electric impulses

The oldest part of the brain and is responsible for automatic survival function

Directs sensory information (Grand Central Station)

Involved in speaking and muscle movements and in making plans/judgments

Secrete hormones which influence metabolism. Other regulates calcium in the blood.

They send motor signals from the Central Nervous System to the muscles of the body

The base of the brain stem and is responsible for controlling the heartbeat and breathing.

Directs activities including eating, drinking, body temperature, and control of emotions

Processes somatic information

Produce sex hormones and cortisol. Other regulates the level of sugar in the blood

Neurons that transmit impulses between neurons

In the middle of the brainstem and they control movements.

Consists of two almond-shaped neural clusters linked to the emotions of fear and anger

Includes the visual areas and receives visual information and processes it

Testes/Ovaries

The area at the rear of the frontal lobes that controls voluntary movements

It is the nerve network in the brainstem that controls arousal

Contributes to the formation of memory

Includes auditory areas that process incoming speech

Wide thick nerve tract that connects both hemispheres

At the front of the parietal lobe that processes feeling. Other is associated with higher-level functions of the nervous system

Helps coordinate voluntary movements and balance

Secretes hormones into your bloodstream

Combine sensory and motor info; coordinate interaction among different brain areas. Frontal Lobe of the left hemisphere and temporal lobe of left hemisphere constitute the two association areas

Pituitary Gland
