Schwann cells produce myelin for axons in:
WebAlthough the large axons in the intermediate and more distal regions of the root are myelinated by Schwann cells (many profiles with perinuclear Schwann cell cytoplasm are seen), those in the more proximal transition zone (Figure 7, TZ) are myelinated by oligodendrocytes. Although the EM section is from an elasmobranch utilizing myelin … WebIn peripheral nerves, Schwann cells form the myelin sheath, which allows the efficient propagation of action potentials along axons. The transcription factor Krox20 regulates the initiation of myelination in Schwann cells and is also required to maintain mature myelin. The adhesion G protein-coupled receptor (GPCR) Gpr126 is essential for ...

Web17 May 2024 · The axon emerges from the axon hillock and is covered by glial cells, in this case an oligodendrocyte of the CNS, that form the myelin. If the neuron was in the PNS, its axon would be covered by other glial cells called Schwann cells. Gaps between the myelin are called nodes of Ranvier.
