Nerve signaling is the process by which neurons, the cells in our nervous system, communicate with each other. When a neuron receives a signal, it generates an electrical impulse called an action potential. This impulse travels along the neuron's long extension, known as the axon, until it reaches the end, where it triggers the release of chemical messengers called neurotransmitters. These neurotransmitters cross the gap, or synapse, between neurons and bind to receptors on the next neuron, passing along the signal. This rapid communication allows our body to respond quickly to stimuli, coordinating everything from muscle movements to sensory perceptions, making nerve signaling essential for daily functioning.
