nervous system

interprets sensory info, gives instructions

connective nueron between PNS neurons

deliver signals to CNS

send signals from skin, skeletal muscles, joints

send signals from visceral organs

impulses from CNS to muscles, glands, organs to activate response

includes nerves associated with the skeletal muscles

includes nerves associated with organs, glands, cardiac and smooth muscles

STIMULATES

INHIBITS

look like branches, receive and conduct electrical pulses

contains nucleus, cytoplasm, and other organelles

long thin fiber that extends from cell body and conducts impulses away from cell body to other neurons

ends of the axons which secrete neurotransmitters

fatty substance that surrounds and protects the neuron - insulates and helps it travel faster

gaps in meylin, signa will jump from node to node

area where signal begins - site of stimulus

site where signal ends - caused a response in muscle/gland

all nerves outside the brain and spinal cord
