Noun

Macroglia

macroglia

[mə′kräg·lē·ə] (neuroscience) That portion of the neuroglia composed of astrocytes.

Macroglia

the cells in the brain that fill the spaces between the neurons and the capillaries surrounding them.

Macroglia is the principal tissue of the neuroglia and is often identified with it. In contrast to the microglial cells, the macroglial cells originate, like the neurons, with the neural tube. The larger cells of the macroglia, which form the astroglia and ependyma, play an important part in the blood-brain barrier and in the reaction of nervous tissue to injury and infection. The smaller (satellite) cells of the neurons (oligodendroglia) elaborate the myelin sheaths of the axons (processes of the neurons) and supply the neurons with nutritive substances, especially during periods of intensified brain activity.

macroglia

A generic term for cells in the CNS which are neither neurons nor microglia (or tissue-based macrophages). Macroglia cells include astrocytes, oligodendrogliocytes and glioblasts; they provide nutrition, physical support and synthesise myelin.
