Tendons are fibrous connective tissues that connect muscles to bones. They are composed primarily of collagen, a strong and flexible protein, arranged in parallel bundles that provide tensile strength. This structure allows tendons to efficiently transmit the force generated by muscle contractions to the skeleton, enabling movement. Tendons are crucial for locomotion, posture, and a wide range of bodily functions.

The structure of a tendon is hierarchical, starting with collagen molecules that assemble into fibrils, which then form fibers. These fibers are grouped into fascicles, and multiple fascicles constitute the entire tendon. This organization is supported by connective tissue sheaths that provide nourishment and protection. Tendons are typically avascular, meaning they have limited blood supply, which can affect their healing process.

Common conditions affecting tendons include tendinitis, which is inflammation, and tendinopathy, a more general term for tendon pain and dysfunction. Tears, either partial or complete, can also occur, often due to overuse, sudden trauma, or aging. Rehabilitation after tendon injury typically involves progressive loading exercises to promote healing and restore function. Prevention strategies focus on proper warm-up, gradual progression of activity, and strength training to improve tendon resilience.
