What do terminal branches of the axon do?
They form junctions with other cells.
What is the role of the cell body in a neuron?
It maintains the health of the neuron.
What does the myelin sheath do?
It covers the axon of some neurons and helps speed neural impulses.
What is a neural impulse?
An electrical signal traveling down the axon.
