Ion channels are hydrophilic pores in a plasma membrane, they are gated which means they are only open when stimulated for example by voltage. The channels are also selective, allowing only some ions to pass; for example sodium or potassium[1][2]. Ion channels can be classed into three main families: voltage gated ion channels, ligand gated ion channels and mechanically gated ion channles[3].
