Definitions:

Myelinated Axons

Axons that are covered with a fatty substance called myelin, which increases the speed at which electrical impulses propagate along the nerve cell.

Unmyelinated Axons

Nerve fibers lacking a myelin sheath, resulting in slower signal transmission compared to myelinated axons.

Electrochemical Impulses

Biological signals that neurons use to communicate information through an electrical charge transfer across their membrane.

Neurons

Unique cells within the nervous system that convey data to other neurons, muscles, or glands.
