Detailed explanation-1: -In addition to providing support for neurons, glial cells aid in the maintenance of homeostasis, and form myelin. As a whole, glial cells are the most abundant cells in the central nervous system. The most notable glial cells include oligodendrocytes, Schwann cells, astrocytes, microglia, and ependymal cells.
Detailed explanation-2: -These are the glial cells (neuroglial cells), together termed the neuroglia. Supporting, or glia, cells bind neurons together and insulate the neurons. Some are phagocytic and protect against bacterial invasion, while others provide nutrients by binding blood vessels to the neurons.
Detailed explanation-3: -The glial scar is made up of a number of contributing cells. Astrocytes in the spinal cord become activated after injury and their progeny make up a major component of the mature scar. Proliferating ependymal cells give rise to a distinct class of astrocytes which contribute to the central portion of the scar.
