2分钟神经科学:髓鞘

在这个视频中,我讨论髓鞘,一个覆盖的绝缘层轴突许多神经元在神经系统中。我描述了米利尔在促进高效神经元信令方面的作用,我讨论了它的结构,它由髓鞘的延伸组成节间髓鞘周围间歇间隙叫Ranvier节点。我还讨论形成髓鞘的细胞:施旺细胞在里面外周神经系统oligodendrocytes.在里面中枢神经系统

In my 2-Minute Neuroscience videos I simplistically 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.
