|
dendrites
|
carry information and gathers info for the cell body
|
|
|
cell body
|
makes a neurotransmitter ans ships it into the axon bulb for storage AND gets info from dendrites and decides when to send an impulse
|
|
|
axon
|
sends info away from the cell body to the synaptic bulb/synapse
|
|
|
myelin sheath
|
"insulation" or fatty layer produced by neuroglial cells that wrap around the axon
|
|
|
schwann cells
|
wraps myelin around axon in peripheral nervous system
|
|
|
oligodendrocytes
|
wraps myelin around axon in the central nervous system
|
|
|
advantage of being myelinated
|
"white matter" Impulses are carried faster and more effectively down the axon
|
|
|
advantage of being unmyelinated
|
"gray matter" take up less space and process info locally
|
|
|
nodes of Ranvier
|
gaps in the myelin sheath
|
|
|
saltatory conduction
|
info on an axon jumps from node to node
|
