Neurotransmitter:

Function:

Acetylcholine

Learning, memory, muscle movement

Arousal, mood, though processes, physical movement

Serotonin and Norepinephrine

Sensory

PNS to CNS info from sensory receptors, muscles, and glands

Motor

CNS to PNS carry movement commands to body

Nervous System:

Role:

Somatic (skeletal)

PNS to CNS and back, controls skeletal muscles’ movements

Autonomic

Regulates function of internal organs: heart, lungs, etc.

Sympathetic

In control when highly aroused,

prepares us for defensive action, “fight or flight”

Parasympathetic

Returns body to resting state after extreme arousal
