WebMay 17, 2024 · Describe the process of myelination and axon regeneration. Nervous tissue is composed of two types of cells: neurons and glia, as shown in Figure 11.3. 1. Neurons … WebAlthough myelinated nervous systems are shared among 60,000 jawed vertebrates, studies aimed at understanding myelination have focused more and more on mice and zebrafish. To obtain a broader understanding of the myelination process, we examined the little skate, Leucoraja erinacea. The reasons behind initiating studies at this time include: the desire … 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) … See more 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 in the … See more CNS myelin differs slightly in composition and configuration from PNS myelin, but both perform the same "insulating" function (see above). Being rich in lipid, myelin appears … See more Demyelination Demyelination is the loss of the myelin sheath insulating the nerves, and is the hallmark of some neurodegenerative autoimmune diseases, … See more • Lesional demyelinations of the central nervous system • Myelin-associated glycoprotein • Myelin incisure • The Myelin Project, project to regenerate myelin See more Myelin is considered a defining characteristic of the jawed vertebrates (gnathostomes), though axons are ensheathed by a … See more The main purpose of myelin is to increase the speed at which electrical impulses (known as action potentials) propagate along the myelinated fiber.
