Questions: Multiple Choice Question Within a musculoskeletal lever system, what is the fulcrum? Muscles Bones Joints

The answer is the third one (or C): Joints.

Explanation for each option:

• Muscles: Muscles are the force generators in the musculoskeletal system. They contract to create movement but are not the pivot point of the lever system.
• Bones: Bones act as the rigid structures or levers that are moved by the muscles. They provide the framework for the body but are not the pivot point.
• Joints: Joints are the fulcrum in the musculoskeletal lever system. They act as the pivot points around which bones move when muscles contract.

Summary: In a musculoskeletal lever system, the fulcrum is the joint, which serves as the pivot point for movement.
