what parts of the body act as levers
There are four parts to a lever â lever arm, pivot, effort and load. In our bodies: bones act as lever arms. joints act as pivots. muscles provide the effort forces to move loads. loads are the body parts that are being moved. Levers can also be used to magnify movement, for example, when kicking a ball, small contractions of leg muscles produce a much larger movement at the end of the leg.
