Document Summary

Ya got your central nervous system and your peripheral nervous system. Pns- all neurons and all nerves outside cns. Communication network think as cns as communication network (rogers) Send out messages, to muscles and glands, producing movementetc. To be aware of ourselves and our enviroment. Receive info from environment via sensory organs and send info to cns, for further analysis. Found in the cns only in the cns. Receive info from cns and carry to muscles and galnds. Manufacture everything the neurons need to grow function and survive. Expand surface area of neuron without taking too much space. When a neuron fires an action potential or electrical impulse and the axon carries that action potential. Covers some of area in nervous system. Tiny space in the synapse between neurons (neuron transmitters are released in the gap see later) More like sea water, dissolved chemicals in it like na+ cl-, k+
