The common name for the fibrous tissue that connects muscles to bones is tendon. Tendons are tough connective tissues that play a critical role in the musculoskeletal system, allowing for the transmission of force from muscles to bones and enabling movement. They are composed primarily of collagen fibers, which provide strength and flexibility. Tendons come in various shapes and sizes, depending on the muscles they connect and the specific functions they serve. Proper care and conditioning of tendons are essential for preventing injuries, such as tendinitis or ruptures, which can significantly impact mobility and physical activity.
