What is the function of tendons in the musculoskeletal system?

Tendons serve a crucial function in the musculoskeletal system by connecting muscle to bone. This connection allows for the transmission of force from muscles to the skeletal system, enabling movement. When a muscle contracts, the tendon pulls on the associated bone, resulting in motion at the joint. This action is essential for various physical activities, including walking, running, and lifting.

In contrast, the other options refer to different structures within the musculoskeletal system. Ligaments, for example, attach bone to bone and contribute to joint stability. Joint support functions generally relate to the roles of cartilage and ligaments, while joint capsules, which are composed of fibrous tissue, enclose and protect a joint. Therefore, the unique role of tendons is vital for initiating and controlling movement through their direct attachment to muscles and bones.
