Astrocyte

A star-shaped cell of the connective tissue of the nervous system.


Starshaped nerve cell with many branching processes. These processes cover the surfaces of the blood vesselss, neurons, and the pia mater, providing a nonrigid supportive matrix. The matrix helps to regulate the composition of the fluid which surrounds nerve cells (extracellular fluid).


A type of cell with numerous sheet-like processes extending from its cell body, found throughout the central nervous system. It is one of the several different types of cell that make up the ‘glia. The cells have been ascribed the function of providing nutrients for neurons and possibly of taking part in information storage processes.


A neuroglial cell of the central nervous system that supports neurons and contributes to the blood-brain barrier.
