WebThose axons which are not protected by myelin sheath are known as unmyelinated axons. These axons are usually thinner, less than one micron in diameter. They are also known as non-myelinated axons. They conduct nerve impulses at a low speed and the chances of losing nerve impulse exist in the case of unmyelinated axons. Web18 aug. 2024 · As Wikipedia points out: Myelin is a lipid-rich (fatty) substance formed in the central nervous system (CNS) by glial cells called oligodendrocytes, and in the peripheral nervous system (PNS) by Schwann cells.

Web18 jan. 2024 · Myelin is a lipid-rich substance that surrounds nerve cell axons. Conventionally, it is often compared to electrical insulation on nerve fibers, inhibiting the ionic current on internodes ( Bean, 2007 ). Thus, the action potential can only be activated on nodes of Ranvier, which are unmyelinated gaps between myelin sheaths.
