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.
