Myelinogenesis - Wikipedia

Myelin is a lipid-rich material that surrounds nerve cell axons (the nervous system's "wires") to insulate them and increase the rate at which electrical impulses (called action potentials) are passed along the axon. The myelinated axon can be likened to an electrical wire (the axon) with insulating material (myelin) … Meer weergeven The process of generating myelin is called myelination or myelinogenesis. In the CNS, oligodendrocyte progenitor cells (OPCs) differentiate into mature oligodendrocytes, which form myelin. In humans, myelination begins early … Meer weergeven CNS myelin differs slightly in composition and configuration from PNS myelin, but both perform the same "insulating" function … Meer weergeven Demyelination Demyelination is the loss of the myelin sheath insulating the nerves, and is the hallmark of some neurodegenerative autoimmune diseases, … Meer weergeven • Lesional demyelinations of the central nervous system • Myelin-associated glycoprotein • Myelin incisure Meer weergeven Myelin is considered a defining characteristic of the jawed vertebrates (gnathostomes), though axons are ensheathed … Meer weergeven The main purpose of myelin is to increase the speed at which electrical impulses (known as action potentials) propagate along the myelinated fiber.
