Web24 okt. 2024 · What happens if there is no myelin sheath? When the myelin sheath is damaged, nerves do not conduct electrical impulses normally. Sometimes the nerve fibers are also damaged. If the sheath is able to repair and regenerate itself, normal nerve function may return. However, if the sheath is severely damaged, the underlying nerve fiber can die. WebThe sheath continues to expand along the length of the target axon while new membrane is synthesized at the leading edge of the inner tongue of the developing myelin sheath, which begins to take on a spiral cross-sectional structure. Myelination in the central nervous system by an oligodendrocyte
WebMyelin sheaths are generated by Schwann cells in the peripheral nervous system and by oligodendrocytes in the central nervous system. The myelin layer acts as an insulator, allowing the action potential (nerve impulse) to jump from one node of Ranvier to the next, with minimal loss of energy. WebAnswer (1 of 5): The myelin sheath is an insulation material around nerves where the nerves are in the center and the myelin sheath wraps around it.
