Word: Actomyosin

Part of Speech: Noun

Simple Definition: Actomyosin is a special protein found in muscle fibers. It is made up of two proteins called myosin and actin. When your muscles get a signal to move, actomyosin helps them contract, which means they shorten and get tighter. This is what allows you to move your body.
