Neuron And Neuroglia Structure Of A Neuron And Glial Cells Stock Illustration Download Image The name oligodendrocyte is derived from the greek words "oligo" (meaning small), "dendro" (meaning tree), and "cyte" (meaning cell), which together translate to "small tree like cell" and reflect the cell's appearance. the oligodendrocytes, also called oligodendroglia, are part of the neuroglia, the supporting cells of the nervous system. Peters, a. & sethares, c. oligodendrocytes, their progenitors and other neuroglial cells in the aging primate cerebral cortex. cereb. cortex 14 , 995–1007 (2004).
Cells Of Human S Brain Neuron And Glial Cells Microglia Astrocyte And Oligodendrocyte Stock Neuroglia are sub classified into cns and pns glia, but overall their functions are the same – to provide homeostatic, structural and metabolic support of neurons, to meylinate their axons to ensure rapid signal transmission and to be the main defensive and immunocompetent cells. in the cns, the main glial cell types are astrocytes. Neurons are associated with support cells called glia. neuroscientists have long believed that glia outnumber neurons by 10:1 (or more). however, recent investigations suggest that in some regions of the brains of humans and other primates, that ratio is closer to 1:1. however, the ratio of glia to neuron from region to region varies considerably. Glial cells, consisting of microglia, astrocytes, and oligodendrocyte lineage cells as their major components, constitute a large fraction of the mammalian brain. originally considered as purely non functional glue for neurons, decades of research have highlighted the importance as well as further functions of glial cells. There are three types of glial cells in the mature central nervous system: astrocytes, oligodendrocytes, and microglial cells (figure 1.4a — c).astrocytes, which are restricted to the brain and spinal cord, have elaborate local processes that give these cells a starlike appearance (hence the prefix “astro”).
