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
