What physiological role do tendons serve?

  1. Connect muscle to muscle

  2. Connect bone to bone

  3. Connect muscle to bone

  4. Provide structure to cartilage

The correct answer is: Connect muscle to bone

Tendons play a crucial physiological role by connecting muscle to bone. This connection allows forces generated by muscles during contraction to be transmitted to the skeletal system, facilitating movement at the joints. When a muscle contracts, the tendon transmits the pulling force to the bone, resulting in motion. The structure of tendons—composed mainly of collagen fibers—provides the necessary tensile strength to withstand the forces applied during physical activity. This essential function is fundamental to all forms of locomotion and is vital for generating movement and maintaining stability in the body. Understanding this role is critical in fields such as sports science and rehabilitation, where optimizing muscle-tendon interactions can enhance performance and recovery.
