chapter 10-parts of the neuron
myelin sheath
White fatty material that surrounds the axon; increases the rate at which the electrical signal travels along the axon
acetylcholine (ACh)
a common neurotransmitter
nodes of Ranvier
allows for saltatory conduction of the nerve impulse
neurilemma
layer of cells that covers the axons of peripheral neurons; concerned with nerve regeneration
myelin sheath
makes white matter white
axon terminal
part of the axon where the neurotransmitters are stored
cell body
part of the neuron that contains the nucleus; dendrites bring information to this structure. and the axon carries information away from this structure
axon
part of the neuron that transmits information away from the cell body
nodes of Ranvier
short segments of the axonal membrane that are not covered by myelin sheath
dendrites
treelike part of the neuron that receives information from another neuron; transmits that information toward the cell body
