nerve impulse: A wave of physical and chemical excitation along a nerve fiber in response to a stimulus, accompanied by a transient change in electric potential in the membrane of the fiber.Muscle conduction: occurs when a muscle cell (called a muscle fiber) lengthens or shortens.

A nerve impules is a wave of physical and chemical movement alone a nerve fiber. A muscle contraction is when a muscle cell lengthens and shortens along a nerve fiber. They both happen around a nerve.

A muscle contraction is when a muscle lenghtens and shortens. A nerve impulse is a wave of physical and chemical movement. That is the difference between a nerve impulse and a muscle contraction.

A nerve impusle is a wave of singals from the brain to the muscle. A muscle contraction is what a muscle acutally does when a nerve impulse gets to muscle and tells the muscle to contract. A nerve impulse causes a muscle contraction.
