Parts of neurons

dendrites

receives signals from axons of other neurons, carry signals to cell body

cell body

contains nucleus/DNA and determines the function of the cell

axon

carry signal away from cell body to axon termanal to propagate message

myelin

white fatty material covering of axons that protects and and insulates

white matter

appears whitish and contains myelinated axons

gray matter

appear grayish and contains unmyleinated structures

sensory neurons

carry impulses in CNS

interneurons

link neurons

motor neurons

carry impulses away from CNS

node of ranvier

gaps in myelin sheath along the axon

salutary conduction

signals jump from node to node
