Study Notes

Central Nervous System (CNS)

The CNS consists of the brain and spinal cord.

Neuroglia

Neuroglia, also known as glial cells, provide support, protection, and maintenance functions for neurons.

Gray Matter

Gray matter is composed of neuronal cell bodies, dendrites, and synapses.

White Matter

White matter appears white due to the high concentration of myelin, a fatty insulating substance that surrounds axons.

Peripheral Nervous System (PNS)

The PNS consists of nerves that connect the CNS to the rest of the body, including sensory receptors, motor neurons, and interneurons.
