Takes place when nerve impulses stop

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.”. Instead your nerves send lots of electrical impulses (called action potentials) to different muscles in your hand, allowing you to move your hand with extreme precision. WebSimilarly, the axon transports the impulses from the soma onward along its path. The axon terminal is like the tree buds at the end of the tree’s branches. Leaves and pollen come out of these buds. The electrical impulses are sent (or “released” like pollen from a bud) to be picked up by the next nerve cell.
