What structure attaches muscles to bones?

Tendons are the connective tissues that attach muscles to bones, allowing for the transfer of force from the muscle to the bone. When a muscle contracts, the tendon pulls on the bone, resulting in movement at the joint. Tendons are composed of dense connective tissue that provides strength and flexibility, ensuring that they can effectively withstand the forces exerted during muscle contractions.

In contrast, ligaments connect bones to other bones and help stabilize joints, while cartilage serves as a cushion and reduces friction between bones. Joints are the points where bones meet, enabling movement but not acting as attachments for muscles. Therefore, the role of tendons in connecting muscles to bones is crucial for the musculoskeletal system's functioning.
