Detailed explanation-1: -Whereas protoplasmic astrocytes appear distributed relatively uniformly within cortical gray matter, fibrous astrocytes are organized along white matter tracts, within which they are oriented longitudinally in the plane of the fibre bundles.
Detailed explanation-2: -Several forms of astrocytes exist in the central nervous system including fibrous (in white matter), protoplasmic (in grey matter), and radial.
Detailed explanation-3: -The two main types of astrocytes are the ones found in the white matter, called fibrous astrocytes, and the ones found in the gray matter, the protoplasmic astrocytes.
