Cells of the Nervous System. The nervous system is made up of two types of cells: neurons and glia. Neurons are the fundamental cellular unit of the central nervous system (CNS) and peripheral nervous system (PNS). Essential features of neurons:1  The purpose of neurons is to receive, process, and transfer information.2  This information is made up of chemical or electrical signals.ells of the Nervous System.

The main purpose of myelin is to cover neuron cells so that it can conduct action potential more quickly. If you examine a myelinated neural axon within peripheral nervous system, you will see Schwann cells that cover the cell's axon with myelin sheaths.In between the myelin sheaths are what is called Nodes of Ranvier.So if you follow propagation of an action potential you will see that it starts with the addition of charges through the dendrites into the soma (cell body) and into the axonal hillock.he function of the myelin sheath is to speed up the impulses as  they propagate along the myelinated fibers. This keeps the  electrical current from leaving the axon.
