Glial cells myelin sheath
WebJun 8, 2024 · Glial cells of the (b) peripheral nervous system include Schwann cells, which form the myelin sheath, and satellite cells, which provide nutrients and structural support to neurons. Key Points Glia guide developing neurons to their destinations, buffer harmful ions and chemicals, and build the myelin sheaths around axons. WebSchwann cells are the glial cells that form the myelin sheath on axons outside the brain. Unlike oligodendrocytes, Schwann cells do not have multiple cellular extensions, but instead each cell engulfs a segment of axon and forms a multilayered myelin sheath around it (Figure 3). Small diameter axons, which conduct impulses slowly, do not have a ...
