Schwann Cell

A type of glial cell in the peripheral nervous system which forms the myelin sheath around neuronal axons, enabling faster transmission of electrical signals.

Myelin Sheath

The insulating layer around many nerve fibers, consisting of protein and fatty substances, which enables faster transmission of electrical impulses.

Axon

A long, slender projection of a neuron that conducts electrical impulses away from the neuron's cell body.
