Neurons and Nervous System
... Gated ion channels change the resting potential when they open and close. The membrane is depolarized when Na+ enters the cell and the inside of the neuron becomes less negative than when at rest. If gated K+ channels open and K+ leaves, the cell becomes more negative inside and the membrane is ...

Multiple sclerosis (MS) is a famous one, in which an inappropriate autoimmune response results in the destruction of myelin, thereby interrupting signaling in nerves. One can see these diseases in images of the nervous system because th ...
