<span>A nerve impulse is an electrical signal that travels along an axon. There is an electrical difference between the inside of the axon and its surroundings, like a tiny battery. When the nerve is activated, there is a sudden change in the voltage across the wall of the axon, caused by the movement of ions in and out of the neuron. This triggers a wave of electrical activity that passes from the cell body along the length of the axon to the synapse. Does this help you?</span>

The medical term for this condition is called hyperinsulinism. 'Hyper' in Greek root means 'over' or 'excess of'. So, having an excessive secretion of insulin in the bloodstream is basically having an oversupply of insulin.
