Somatic Nervous System
voluntary system, controls skeletal muscles; interacts with external environment.
Autonomic Nervous System
Involuntary system, regulates body's internal environment, including organs, glands, blood vessels.
Sympathetic Nervous System
Prepares body for action; mobilizes energy resources.
Parasympathetic Nervous System
Conserves body's energy; returns body to normal, quiet state after an emergency.
located in brain, releases growth hormone, regulate glands
neck, releases throxin, effects metabolism
releases adrenaline, epinephrine, norepinephrine, corticoids
releases insulin into blood regulate sugar
