WebNov 13, 2024 · Neuroglia, also called glia or glial cells, are non-neuronal cells of the nervous system. They compose a rich support system that is essential to the operation of nervous tissue and the nervous system. Unlike neurons, glial cells do not have axons, dendrites, or conduct nerve impulses. WebNeuroglial cells—usually referred to simply as glial cells or glia—are quite different from nerve cells. The major distinction is that glia do not participate directly in synaptic interactions and electrical signaling, although their supportive functions help define synaptic contacts and maintain the signaling abilities of neurons. Glia are more numerous than … holidays snacks foods

WebThe most commonly observed changes are (1) stretching and flattening of ependyma, most pronounced over white matter, (2) characteristic ependymal cell surface changes associated with ventricular distension, (3) increased extracellular space and periventricular edema and (4) demyelination and subependymal gliosis. WebIn mammals, cells at the ependymal region proliferate in normal conditions and react after injury, but in humans, the central canal is lost in the majority of individuals from early childhood. It is replaced by a structure that does not proliferate after damage and is formed by large accumulations of ependymal cells, strong astrogliosis and ...
