Answer :
Nerve impulses are transient changes in electrical charge that move along the axon of the neuron. An electrical charge that moves along a neuron's membrane is known as an action potential.
It can occur when chemical inputs from a neighbouring cell alter the membrane potential of a neuron. The membrane potential refers to the variation in the net electrical charge of these ions between the inside and exterior of the cell. The clustering of ions on opposing sides of the cell membrane is the cause of this variation in net electrical charge. The electrical charge difference across the cell membrane leads to the membrane potential. Nerve impulse transmission.
