What is a neural impulse?

A neural impulse, also known as an action potential, is a rapid electrical signal that travels along the axon of a neuron. It occurs when a neuron is activated by stimuli, causing a temporary change in the electrical charge across its membrane. This change allows the neuron to communicate with other neurons, muscles, or glands, facilitating the transmission of information within the nervous system. The process is essential for functions such as reflexes, muscle contraction, and sensory perception.
