Document Summary

All nerves in body outside of the brain and spinal cord. Pick up sensory information, and send it to central nervous system via nerves. Carry information from central nervous system to muscles, glands etc. via nerves. Carry information between sensory neurons to motor neurons (in a reflex action); organize and integrate information; only in central nervous system. Contains genetic information; manufactures vital things for cell to grow, survive, develop. Tube-like structures that branch out of the soma; increases surface area of cell; receives information from other neurons. Thin tube-like structures connected to soma that carry an electric impulse of message away from cell body to be delivered to other cells; White, fatty layer that covers axons; provide insulation; speeds up transmission of impulse. End of axons, where messages are transferred to another neuron. Chemical messengers used to transmit messages between neurons. Located at the base of brainstem; regulates and controls vital body functions (heart beat, circulation, breathing)
