  2. Myelinogenesis - Wikipedia

    en.wikipedia.org/wiki/Myelinogenesis

    Myelination of a peripheral nerve by a Schwann cell. 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 ...

  3. Myelin - Wikipedia

    en.wikipedia.org/wiki/Myelin

    Myelin. Myelin (/ ˈmaɪ.əlɪn / MY-ə-lin) is a lipid -rich material that surrounds nerve cell axons (the nervous system's electrical wires) 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 ...

  4. Remyelination - Wikipedia

    en.wikipedia.org/wiki/Remyelination

    Remyelination is the process of propagating oligodendrocyte precursor cells to form oligodendrocytes to create new myelin sheaths on demyelinated axons in the Central nervous system (CNS). This is a process naturally regulated in the body and tends to be very efficient in a healthy CNS. [1] The process creates a thinner myelin sheath than ...

  5. Saltatory conduction - Wikipedia

    en.wikipedia.org/wiki/Saltatory_conduction

    Myelinated axons only allow action potentials to occur at the unmyelinated nodes of Ranvier that occur between the myelinated internodes. It is by this restriction that saltatory conduction propagates an action potential along the axon of a neuron at rates significantly higher than would be possible in unmyelinated axons (150 m/s compared from 0.5 to 10 m/s). [1]

  6. Node of Ranvier - Wikipedia

    en.wikipedia.org/wiki/Node_of_Ranvier

    Latin. incisura myelini. MeSH. D011901. TH. H2.00.06.2.03015. Anatomical terms of microanatomy. [edit on Wikidata] In neuroscience and anatomy, nodes of Ranvier (/ ˈrɑːnvieɪ / RAHN-vee-ay), [1][2] also known as myelin-sheath gaps, occur along a myelinated axon where the axolemma is exposed to the extracellular space.

  7. White matter - Wikipedia

    en.wikipedia.org/wiki/White_matter

    White matter is named for its relatively light appearance resulting from the lipid content of myelin. However, the tissue of the freshly cut brain appears pinkish-white to the naked eye because myelin is composed largely of lipid tissue veined with capillaries. Its white color in prepared specimens is due to its usual preservation in formaldehyde.

  8. Myelin basic protein - Wikipedia

    en.wikipedia.org/wiki/Myelin_basic_protein

    Myelin basic protein (MBP) is a protein believed 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] MBP maintains the correct structure of ...

  9. Myeloid tissue - Wikipedia

    en.wikipedia.org/wiki/Myeloid_tissue

    Myeloid tissue, in the bone marrow sense of the word myeloid (myelo- + -oid), is tissue of bone marrow, of bone marrow cell lineage, or resembling bone marrow, and myelogenous tissue (myelo- + -genous) is any tissue of, or arising from, bone marrow; in these senses the terms are usually used synonymously, as for example with chronic myeloid ...
