Explanation
A nerve impulse is an electrical signal that travels along the length of a neuron. It is fundamental to the functioning of the nervous system because it carries information from one part of the body to another. Nerve impulses allow neurons to communicate with each other and with other cells, enabling sensory perception, motor control, and information processing.
