Nerve impulses are usually transmitted

Nerve impulses are usually transmitted along neurons through a process called action potential. This involves the rapid depolarization and repolarization of the neuron's membrane, which is facilitated by the movement of ions, primarily sodium and potassium. The impulse travels down the axon and is transmitted to other neurons or target tissues at the synapse through the release of neurotransmitters. This complex process allows for rapid communication within the nervous system.
