  2. Myelinogenesis - Wikipedia

    en.wikipedia.org/wiki/Myelinogenesis

    Myelinogenesis is the formation and development of myelin sheaths in the nervous system, typically initiated in late prenatal neurodevelopment and continuing throughout postnatal development. [1] Myelinogenesis continues throughout the lifespan to support learning and memory via neural circuit plasticity as well as remyelination following ...

  3. Myelin - Wikipedia

    en.wikipedia.org/wiki/Myelin

    Myelin (/ ˈ m aɪ. ə l ɪ n / MY-ə-lin) is a lipid-rich material that surrounds nerve cell axons to insulate them and increase the rate at which electrical impulses (called action potentials) pass along the axon. [1] [2] The myelinated axon can be likened to an electrical wire (the axon) with insulating material (myelin) around it. However ...

  4. Myelin-associated glycoprotein - Wikipedia

    en.wikipedia.org/wiki/Myelin-associated_glycoprotein

    MAG is believed to be involved in myelination during nerve regeneration in the PNS [6] and is vital for the long-term survival of the myelinated axons following myelinogenesis. [7] In the CNS MAG is one of three main myelin-associated inhibitors of axonal regeneration after injury, [ 8 ] making it an important protein for future research on ...

  5. Oligodendrocyte progenitor cell - Wikipedia

    en.wikipedia.org/wiki/Oligodendrocyte_progenitor...

    OPCs play a critical role in developmental and adult myelinogenesis. They give rise to oligodendrocytes, which then wrap around axons and provide electrical insulation by forming a myelin sheath. This enables faster action potential propagation and high fidelity transmission without a need for an increase in axonal diameter. [ 2 ]

  6. Oligodendrocyte - Wikipedia

    en.wikipedia.org/wiki/Oligodendrocyte

    Oligodendrocytes are a type of glial cell, non-neuronal cells in the central nervous system.They arise during development from oligodendrocyte precursor cells (OPCs), [8] which can be identified by their expression of a number of antigens, including the ganglioside GD3, [9] [10] [11] the NG2 chondroitin sulfate proteoglycan, and the platelet-derived growth factor-alpha receptor subunit (PDGF ...

  7. Biological neuron model - Wikipedia

    Fig. 1. Neuron and myelinated axon, with signal flow from inputs at dendrites to outputs at axon terminals. The signal is a short electrical pulse called action potential or 'spike'. Fig 2. Time course of neuronal action potential ("spike"). Note that the amplitude and the exact shape of the action potential can vary according to the exact ...

  9. Group A nerve fiber - Wikipedia

    en.wikipedia.org/wiki/Group_A_nerve_fiber

    There are four subdivisions of group A nerve fibers: alpha (α) Aα; beta (β) Aβ; , gamma (γ) Aγ, and delta (δ) Aδ. These subdivisions have different amounts of myelination and axon thickness and therefore transmit signals at different speeds. Larger diameter axons and more myelin insulation lead to faster signal propagation.
