Dendrites, Axon

synaptic vesicles

membrane enclosed sacs located with in the synaptic end bulbs

Axon

a thin long process, ranges in length from lml to lm depending on location

Dendrites

branched, thick extensions, coming directly off of the cell body

axon terminals

branches that the axon divides into

function of Axon

carries nerve impulses away from the cell body towards other neurons, muscle and glands

neurotransmitter

chemical that is stored in the synaptic vesticles

synaptic end bulbs

enlarged region at the end of each terminal

functions of Dendrites

to receive a nerve impulse and carry nerve impulses toward the cell body

trigger zone

where a nerve impulse is started

axon hillock

where axon joins the cell body (meeting place)

myelin

white phospholipid covering an axon found only on some neurons
