The Nervous SystemNervous System

Central Nervous SystemThe Brain & Spinal Cord

Peripheral Nervous SystemTransmits info to & from the CNS

BrainInterprets & stores info

& sends orders to muscle glands & organs

Spinal CordPathway connecting

the brain & peripheral nervous system

Autonomic Nervous System

Regulates glands, organs, blood vessels, digestion &

blood pressure

Somatic Nervous System

Carries sensory info & controls movement of the

skeletal muscles

Parasympathetic Division

Maintains body functions & saves energy

Sympathetic DivisionPrepares the body to react &

expend energy in times of stress
