  2. Node of Ranvier - Wikipedia

    en.wikipedia.org/wiki/Node_of_Ranvier

    The myelin sheath of long nerves was discovered and named by German pathological anatomist Rudolf Virchow [21] in 1854. [22] French pathologist and anatomist Louis-Antoine Ranvier later discovered the nodes, or gaps, in the myelin sheath that now bear his name.

  3. 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 ...

  4. 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 ...

    The myelin sheath that surrounds and protects nerve cells is made by cells called oligodendrocytes. In a person with MS, these cells are lost, so damaged myelin sheaths cannot be repaired.

  6. Cellular extensions - Wikipedia

    Lamellar microtubules: They are the microtubules that eventually wrap around the axon, forming the myelin sheath. Actin-based: These include terminal foot processes of podocytes and dendritic spines (small protrusions arising from dendrites). [3] IF-based: The predominant cytoskeletal element within astrocyte processes at birth is microtubules.

    These microscopic nerve fibers, where the action potential occurs, are protected by a white, fatty tissue that surrounds and insulates it, known as the myelin sheath. This insulation helps the axon of a nerve cell with the conduction and speed of the signal along the axon.

  8. Sulfatide - Wikipedia

    en.wikipedia.org/wiki/Sulfatide

    Myelin is typically composed of about 70 -75% lipids, and sulfatide comprises 4-7% of this 70-75%. [2] When lacking sulfatide, myelin sheath is still produced around the axons; however, when lacking sulfatide the lateral loops and part of the nodes of Ranvier are disorganized, so the myelin sheath does not function properly. [5]

    Brain cells make up the functional tissue of the brain.The rest of the brain tissue is the structural stroma that includes connective tissue such as the meninges, blood vessels, and ducts.
