MICROANATOMY

Detailed explanation-1: -There are three main types of gated channels: chemically-gated or ligand-gated channels, voltage-gated channels, and mechanically-gated channels.

Detailed explanation-2: -Non-gated channels are ion channels that are always open. Another common name for these channels is “leak” channels, because they simply allow ions to pass through the channel without any impedance.

Detailed explanation-3: -Ion channels are protein molecules that span across the cell membrane allowing the passage of ions from one side of the membrane to the other. They have an aqueous pore, which becomes accessible to ions after a conformational change in the protein structure that causes the ion channel to open.
