What anatomical structures of the musculoskeletal system correspond to the components of a lever system? Describe the arrangement of these parts in first, second, and third class lever systems
What will be an ideal response
The bone is the lever. The joint is the fulcrum. The muscle contraction pulling on its insertion point is the effort. The weight of the part to be moved is the resistance. A first class lever has the fulcrum between the effort and the resistance; a second class lever has the resistance in the middle; the third class lever has the effort in the middle. In all cases, the lever moves around the fulcrum.
