GENERAL HISTOLOGY

Detailed explanation-1: -Astrocytes provide a cellular link between the neuronal circuitry and blood vessels. This neurovascular coupling enables astrocytes to relay signals that regulate blood flow in response to neuronal activity (Attwell et al.

Detailed explanation-2: -Astrocytes are delicate, star-shaped branching glial cells. Their numerous radiating processes cling to neurons and their synaptic endings. These astrocytes cover nearly all the capillaries in the CNS. They support and brace the neurons and anchor them to their nutrient supply lines.

Detailed explanation-3: -Astrocytes. These star-shaped cells are the largest of the glial cells and have a supportive and insulating function. They hold together the nervous tissue and anchor it to the blood vessels that course through it (Fig. F69).

Detailed explanation-4: -Astrocytes are specialized glial cells that outnumber neurons by over fivefold. They contiguously tile the entire central nervous system (CNS) and exert many essential complex functions in the healthy CNS.
