Glial cells provide mechanical support to neurons and act as insulators to prevent unwanted neuronal impulses. They can remove debris, repair nervous tissue, store neurotransmitters, and maintain an optimal environment for neuronal functions. Various types of glial cells, such as oligodendrocytes and ependymal cells, perform specific roles, including myelination and material exchange between the brain and cerebrospinal fluid.

3. 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
