Sommario/riassunto

In my 2-Minute Neuroscience videos I explain neuroscience topics in 2 minutes or less. In this video, I discuss myelin, an insulatory layer that covers the axons of many neurons in the nervous system. I describe myelin's role in promoting efficient neuronal signaling, and I discuss its structure, which consists of stretches of myelin called internodes surrounding intermittent gaps called nodes of Ranvier. I also discuss the cells that form myelin: Schwann cells in the peripheral nervous system and oligodendrocytes in the central nervous system.
