WebThere are at least 4 different types of voltage-gated K + channels involved in the process, each with slightly different properties. The prolonged nature of the action potential in cardiac muscle has at least 2 important outcomes. First, it prevents the membrane from being restimulated until the muscle has had time to contract and then relax. WebWhen you want your hand to move, your brain sends signals through your nerves to your hand telling the muscles to contract. But your nerves don’t just say “hand, move.”.
