Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]

What cell is found in the CNS and connects neurons to blood vessels and form scar tissue?

A	Microglial
B	Oligodendrocytes
C	Astrocytes
D	Ependymal

Explanation:

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: -Astrocytes provide a cellular link between the neuronal circuitry and blood vessels.

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.
