A&P chapter 10 Study Guide Part 3

acetylcholine (ACh)

A common neurotransmitter

nodes of Ranvier

Allows for saltatory conduction of the nerve impulse

neurilemma

Layer of cells that cover the axons of peripheral neurons; concerned with nerve regeneration

myelin sheat

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 form 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

myelin sheath

White fatty material that surrounds the axon; increases the rate at which the electrical signal travels along the axon
