NettetConnective tissue layer that surrounds each axon: Endoneurium 2. Contains secretory vesicles filled with a neurotransmitter: Synaptic terminals 3. Neuron cell process that … 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) around … Se mer 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 3rd … Se mer CNS myelin differs slightly in composition and configuration from PNS myelin, but both perform the same "insulating" function (see above). … Se mer Demyelination Demyelination is the loss of the myelin sheath insulating the nerves, and is the hallmark of some Se mer • Lesional demyelinations of the central nervous system • Myelin-associated glycoprotein • Myelin incisure Se mer Myelin is considered a defining characteristic of the jawed vertebrates (gnathostomes), though axons are ensheathed by a type of cell, called glial cells, in invertebrates. These glial wraps are quite different from vertebrate compact myelin, formed, as … Se mer The main purpose of myelin is to increase the speed at which electrical impulses (known as action potentials) propagate along the myelinated … Se mer Functionally equivalent myelin-like sheaths are found in several invertebrate taxa including oligochaetes, penaeids, palaemonids, and calanoids. These myelin-like sheaths … Se mer
