2. Functions of glial cells They provide mechanical support to neurons. Because of their non-conducting nature, the glial cells act as insulators between the neurons and prevent neuronal impulses from spreading in unwanted directions. They can remove the foreign material and cell debris by phagocytosis. They can repair the damaged areas of nervous tissue by proliferation (gliosis ) they form glial scar tissue, and fill the gaps left by degenerated neurons. Glial cells can take up and store neurotransmitters released by the neighbouring synapses. These can-either be metabolized or released again from the glial cells. They help in neuronal functions by maintaining a suitable metabolic and ionic environment for the neurons. Oligodendrocytes myelinate tracts. Ependymal cells are concerned with exchanges of materials between brain and Cerebrospinal Fluid. Vijaylaxmi Pattanshetti Q: Functions of Neuroglial cells
