Myelination continues through the adolescent stage of life. Schwann cells supply the myelin for the peripheral nervous system, whereas oligodendrocytes, specifically of the interfascicular type, myelinate the axons of the central nervous system.t is an outgrowth of a type of glial cell. The production of the myelin sheath is called myelination. In humans, myelination begins in the 14th week of fetal development, although little myelin exists in the brain at the time of birth.
The myelin sheath allows signals to be transmitted rapidly from the nervous system to the rest of the body. When myelin is destroyed -- called demyelination -- nerve signals are slowed or stopped. In the central nervous system -- the brain and spinal cord -- myelin cannot repair itself after it is damaged.However, in the peripheral nervous system -- the nerves that travel to the arms and legs -- myelin can often regrow. A number of diseases affect the myelin sheath in the central and peripheral nervous system.owever, in the peripheral nervous system -- the nerves that travel to the arms and legs -- myelin can often regrow. A number of diseases affect the myelin sheath in the central and peripheral nervous system.
