Gray Matter

Brain tissue comprising neuron cell bodies, dendrites, and unmyelinated axons, associated with processing and cognition.

Spinal Cord

A long, thin, tubular structure made up of nervous tissue that extends from the brainstem to the lower back, serving as the main pathway for information connecting the brain and peripheral nervous system.

Myelinated Axons
