Glia

Glia

Glia, additionally called glial cells or neuroglia, are non-neuronal cells in the focal sensory system (mind and spinal rope) and the fringe sensory system. They look after homeostasis, shape myelin, and offer help and security for neurons. In the focal sensory system, glial cells incorporate oligodendrocytes, astrocytes, ependymal cells, and microglia, and in the fringe sensory system glial cells incorporate Schwann cells and satellite cells. They have four primary capacities: (1) to encompass neurons and hold them set up; (2) to supply supplements and oxygen to neurons; (3) to protect one neuron from another; (4) to demolish pathogens and expel dead neurons. They likewise assume a job in neurotransmission and synaptic associations, and in physiological procedures like relaxing. While glia were thought to dwarf neurons by a proportion of 10:1, an ongoing report gives proof to a proportion of under 1:1.

Glia were found in 1856, by the pathologist Rudolf Virchow in his scan for a "connective tissue" in the brain.[6] The term gets from Greek γλία and γλοία "stick"(/ˈɡliːə/or/ˈɡlaɪə/), and recommends the first impression that they were the paste of the sensory system.There are two kinds of glia: Macroglia and microglia.
