Dendrites

rootlike parts of the cell that look like they stretch out from the cell body

soma (cell body)

contains the nucleus and other parts of the cell needed to sustain its life

axon

wirelike structure ending in the terminal branches that extends from the cell body

myelin sheath

a fatty covering around the axon of some neurons that speeds neural impulses

terminal branches

the branched end of the axon that contains neurotransmitters

neurotransmitters

chemicals contained in chemical branches that enable neurons to communicate. neurotransmitters fit Into receptor sites on the dendrites of neurons (like a key fits into a lock).

synapse

the sapce between the terminal branches of one neuron and the dendrites to the next neuron.
