How do nerve cells communicate with each other to transmit signals within the body?

Nerve cells communicate with each other through electrical and chemical signals. When a nerve cell is stimulated, it sends an electrical impulse down its length. At the end of the cell, neurotransmitters are released into the synapse, a small gap between nerve cells. These neurotransmitters bind to receptors on the neighboring cell, triggering a new electrical impulse and continuing the signal transmission.
