The nervous system is anatomically divided in two parts:
- Central nervous system (CNS) - Consists of the brain and spinal cord.
- Peripheral nervous system (PNS) - Consists of all other nervous tissue.
Histologically, tissue in the nervous system is made up of
cells and
cell processes. Cells consist of
neurons and
neuroglia (also known as glial cells). Cell processes consist of
axons and
dendrites.
