In the central nervous system (CNS) — the brain and spinal cord — cells called oligodendrocytes wrap their branch-like extensions around axons to create a myelin sheath. In the nerves outside of the spinal cord, Schwann cells produce myelin.

WebbThis myelin sheath allows electrical impulses to transmit quickly and efficiently along the nerve cells. How is the myelin sheath formed in neurons? Each myelin sheath is formed by the concentric wrapping of an oligodendrocyte (CNS) or Schwann cell (PNS) process (a limb-like extension from the cell body) around the axon. Webb8 juli 2024 · Ependymal cells produce cerebrospinal fluid and play a role in the Blood-brain barrier Schwann cells supply myelin sheaths for axons, but they are found in the PNS instead of the CNS. Satellite cells seem to regulate the surroundings around nerve cells, keeping chemicals in a state of equilibrium.
