Nettet5. jul. 2024 · In both the CNS and PNS myelin enables fast action potential propagation and protects the axon that it surrounds 1. Myelin sheaths of the CNS and PNS are broadly similar in composition and... NettetMyelin is a multilayer lipid membrane structure that wraps and insulates axons, allowing for the efficient propagation of action potentials. During developmental myelination of the central nervous system (CNS), oligodendrocyte progenitor cells (OPCs) proliferate and migrate to their final destinatio …

Nettet4. apr. 2024 · Many axons are wrapped by an insulating substance called myelin, which is actually made from glial cells. Myelin acts as insulation much like the plastic or rubber that is used to insulate electrical wires. A key difference between myelin and the insulation on a wire is that there are gaps in the myelin covering of an axon. NettetReceptors are parts of the nervous system that allow it to collect information The nervous system controls the activity of muscles and glands. Muscles and glands can …
