Question

multiple choice question

in a musculoskeletal lever system, what force does the muscle contraction provide?

torsion
effort
tension
resistance

Explanation:

Identify components of a biological lever

Using the Skeletal Lever Systems knowledge point, a musculoskeletal lever system consists of four basic components:

1. The lever (the bone)
2. The fulcrum (the joint)
3. The resistance or load (the weight of the body part or an external object)
4. The force that overcomes the resistance

Determine the role of muscle contraction

Using the Biomechanical Effort knowledge point, the force applied to the lever to move the resistance is called the effort. In the human body, this applied force is generated directly by the contraction of skeletal muscles.

Answer:

• Torsion
• Effort (Correct answer)
• Tension
• Resistance
