Tendon a decrease in the average thickness of the collagen fiber bundles comprising the tendon. In humans, an experiment in which people were subjected to a simulated micro-gravity environment found that tendon stiffness decreased significantly, even when subjects were required to perform restiveness exercises. These effects have implications in areas ranging from treatment of bedridden patients to the design of more effective exercises for astronauts. The tendons in the foot are highly complex and intricate. Therefore, the healing process for a broken tendon is long and painful. Most people who do not receive medical attention within the first 48 hours of
Quadriceps tendon Without the quadriceps tendon, the knee cannot extend. Often, when the tendon is completely torn, part of the kneecap bone will break off with the tendon as well. It can rupture resulting in quadriceps tendon rupture. It has been studied in the analysis of patellofemoral pain syndrome. Quadriceps tendon In human anatomy, the quadriceps tendon allows the quadriceps femoris muscles ("rectus femoris, vastus lateralis, vastus medialis, and vastus intermedius") to converge on the superior aspects of the patella on the anterior of the thigh, which continues as the patellar ligament. A tendon connects muscle to bone, while a ligament connects
