WebThere are three main events that take place during an action potential: A triggering event occurs that depolarizes the cell body. This signal comes from other cells connecting to the neuron, and it causes positively charged ions to flow into the cell body. WebThe action potential is the mechanism by which nerve cells communicate and conduct information and muscle cells are induced to contract. ... Although the generation of an …
