cell body
contains nucleus and cell parts
axon
wirelike structure eding in terminal buttons that extends from cell body
myelin sheath
fatty covering of axon of some neurons that speeds neural impulses
neurotransmitters
chemicals covered in terminal buttons that allow neurons to communicate
synapse
space between terminal buttons of neuron and dendrites
