  2. Myelin - Wikipedia

    en.wikipedia.org/wiki/Myelin

    In the PNS, myelin protein zero (MPZ or P0) has a similar role to that of PLP in the CNS in that it is involved in holding together the multiple concentric layers of glial cell membrane that constitute the myelin sheath. The primary lipid of myelin is a glycolipid called galactocerebroside. The intertwining hydrocarbon chains of sphingomyelin ...

  3. Myelinogenesis - Wikipedia

    en.wikipedia.org/wiki/Myelinogenesis

    Myelin is formed by oligodendrocytes in the central nervous system and Schwann cells in the peripheral nervous system.Therefore, the first stage of myelinogenesis is often defined as the differentiation of oligodendrocyte progenitor cells (OPCs) or Schwann cell progenitors into their mature counterparts, [4] followed by myelin formation around axons.

  4. Schwann cell - Wikipedia

    en.wikipedia.org/wiki/Schwann_cell

    A well-developed Schwann cell is shaped like a rolled-up sheet of paper, with layers of myelin between each coil. The inner layers of the wrapping, which are predominantly membrane material, form the myelin sheath, while the outermost layer of nucleated cytoplasm forms the neurilemma. Only a small volume of residual cytoplasm allows ...

  5. Myelin proteolipid protein - Wikipedia

    en.wikipedia.org/wiki/Myelin_proteolipid_protein

    The myelin sheath is a multi-layered membrane, unique to the nervous system, that functions as an insulator to greatly increase the efficiency of axonal impulse conduction. [ 2 ] In humans, point mutations in PLP are the cause of Pelizaeus–Merzbacher disease (PMD), a neurologic disorder of myelin metabolism.

  6. Oligodendrocyte - Wikipedia

    en.wikipedia.org/wiki/Oligodendrocyte

    The myelin sheath is not continuous but is segmented along the axon's length at gaps known as the nodes of Ranvier. In the peripheral nervous system the myelination of axons is carried out by Schwann cells. [1] Oligodendrocytes are found exclusively in the CNS, which comprises the brain and spinal cord.

  7. Myelin basic protein - Wikipedia

    en.wikipedia.org/wiki/Myelin_basic_protein

    Myelin basic protein (MBP) is a protein believed [weasel words] to be important in the process of myelination of nerves in the nervous system. The myelin sheath is a multi-layered membrane, unique to the nervous system, that functions as an insulator to greatly increase the velocity of axonal impulse conduction . [ 5 ]

  8. Myelin protein zero - Wikipedia

    en.wikipedia.org/wiki/Myelin_protein_zero

    The myelin sheath is a multi-layered membrane, unique to the nervous system, that functions as an insulator to greatly increase the velocity of axonal impulse conduction. Myelin protein zero, absent in the central nervous system, [ 14 ] is a major component of the myelin sheath in peripheral nerves .

  9. Soma (biology) - Wikipedia

    en.wikipedia.org/wiki/Soma_(biology)

    Myelin sheath Soma In cellular neuroscience , the soma ( pl. : somata or somas ; from Greek σῶμα (sôma) 'body'), neurocyton , or cell body is the bulbous, non-process portion of a neuron or other brain cell type, containing the cell nucleus .
