Classifying Nervous Tissue

The nervous system is anatomically divided into two parts:
  • Central nervous system (CNS) - Consists of the brain and spinal cord.
  • Peripheral nervous system (PNS) - Consists of cranial and spinal nerves, as well as all other nervous tissue.
Histologically, tissue in the nervous system is made up of cells with cell processes and supporting cells called neuroglia (also known as glial cells).
Neurons are complete nerve cells. Each consists of a cell body that contains the nucleus and one or more cell processes. Cell processes exist as axons and dendrites.
