Ependymal cells are ciliated-epithelial glial cells that develop from radial glia along the surface of the ventricles of the brain and the spinal canal & play a critical role in cerebrospinal fluid homeostasis, brain metabolism, and the clearance of waste from the brain.

Neurons generally have four important zones:

A dendritic zone, where multiple local potential changes generated by synaptic connections are integrated. a site where propagated action potentials are generated. an axonal process that transmits propagated impulses to the nerve endings the nerve endings, where action potentials cause the release of synaptic transmitters.

Pseudo-unipolar cells develops, a single process splits into two, both of which function as axons one going to skin or muscle and another to the spinal cord.
