Definitions:

Neurons

Specialized cells in the nervous system that transmit information to other nerve cells, muscle, or gland cells through electrical and chemical signals.

Myelinated Axons

Axons that are wrapped in a fatty sheath called myelin, which speeds up the transmission of electrical signals along the nerve cells.

Neural Impulses

Electrical signals transmitted along neurons, facilitating communication within the brain and nervous system.

Unmyelinated Dendrites

Dendrite fibers without a myelin sheath, leading to slower transmission of nerve impulses.
