axon – the long extension of a neuron that carries nerve impulses away from the body of the cell.

axon terminals – the hair-like ends of the axon

cell body – the cell body of the neuron; it contains the nucleus (also called the soma)

dendrites – the branching structure of a neuron that receives messages (attached to the cell body)

myelin sheath – the fatty substance that surrounds and protects some nerve fibers

node of Ranvier – one of the many gaps in the myelin sheath – this is where the action potential occurs during saltatory conduction along the axon

nucleus – the organelle in the cell body of the neuron that contains the genetic material of the cell

Schwann’s cells – cells that produce myelin – they are located within the myelin sheath.
