Multipolar Neuron Structure

Cell Body

Contains Nucleus, routes signals

central core

Dendrites

receive incoming signals

branched tips at the start

Axon

conducts signal long distances

long middle wire

Axon Hillock

Triggers the electrical signal

base connecting body to axon

Schwann Cells

myelin sheath, insulates axon to boost speed

outer wrap on axon

Nodes of Ranvier

Gaps that let signals jump

Spaces between insulation

Axon Terminal

Releases chemical neurotransmitters

End tips of the axon
