nerves going to various organs

neuron

basic until of the nervous system or

nerve cell body

contains nucleus and cytoplasma

dendrites

sensory projections which carry information to the nerve cell body

axon

carries impulses away from the cell body to other neurons or other target tissue

synapse

junction between neurons where they can communicate with each other using electrical umpulses

neurotransmitters

chemicals that help to conduct information between synapse

myelin

is fatty covering on the outside of nerves to help speed up the transmission of signals

gray matter

does not have myelin, on outside

white matter

does have myelin, on the inside

white matter on the outside and grey matter on the inside

white matter 2

usually functions as connection tracts and pathways between neurons and brain center

grey matter 2

consists of neuronal cell bodies which are the brains of the neves

receive input from sensory nerves

ventral roots

sends out signals to control motor functions
