what is called myelinated neuron?
Answers
Answer:
Anatomical terminology. Myelin is a lipid-rich (fatty) substance 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.
Explanation:
A neuron in which the axon is enveloped by a layer of Schwann cell membranes (sheath).
Anatomical terminology. Myelin is a lipid-rich (fatty) substance 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.
Myelin enables nerve cells to transmit information faster and allows for more complex brain processes. The myelination process is vitally important to healthy central nervous system functioning. Myelination also occurs in the peripheral nervous system.
Myelination is characterized by the acquisition of the highly specialized myelin membrane around axons. It begins before birth within the caudal brain stem and progresses rostrally to the forebrain, with the most rapid and dramatic period of human central myelination within the first 2 years of postnatal life.
