Explain "ion channels" briefly...

The archetypal channel pore is just one or two atoms wide at its narrowest point and is selective for specific species of ion, such as sodium or potassium. However, some channels may be permeable to the passage of more than one type of ion, typically sharing a common charge: positive (cations) or negative (anions).

ION CHANNELS-the neural membrane contains a variety of passages called the ion channels.these ion channels are the pores formed by the proteins present in the membrane of neurone .this Ion channels are selectively permeable two different ions .it means that the Ion channels are not equally permeable to all the ions .the Ion channels that always remain open are called leak channels. while the channels that remain closed but can open due to a specific stimulus are called gated channels .the presence of voltage gated Ion channel give peace sells the property of excitability ability to respond to stimuli such as mechanical pressure, touch, chemical light, sound or even just voltage applied
