A nerve impulse is specific to a target cell only because it releases a chemical messenger directly onto it, producing a response that is usually rapid, short-lived and localised. In contrast, mammalian hormones stimulate their target cells via the blood system.

WebThis is referred to as the all-or-nothing principle in biology: it means that the power of a stimulus is not proportional to the power of the action potential.
