WebMar 26, 2016 · Nerve impulses have a domino effect. Each neuron receives an impulse and must pass it on to the next neuron and make sure the correct impulse continues on its path. Through a chain of chemical events, the dendrites (part of a neuron) pick up an impulse that's shuttled through the axon and transmitted to the next neuron. ...

A nerve impulse occurs because of a difference in electrical charge across the plasma membrane of a neuron. ... Sodium ions flow in and cause the action potential, and then potassium ions flow out to reset the resting potential. In neurons with a myelin sheath on their axon ... 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. bishop andrew\u0027s charge to synod 2021
