When parts of your body function as lever systems, what part supplies the force?

Asked by sarahbantilan

Answer (2)

Muscles supply the force. They exert force by getting shorter (contracting). A muscle can't get longer by itself. There needs to be another muscle pulling in the opposite direction.

Muscles supply the force in the body's lever systems by contracting and pulling on bones, which act as levers. Joints serve as fulcrums that enable movement. The coordinated action of opposing muscle pairs allows for efficient and effective motion.
