Tendon ornithischian dinosaurs, ossified axial muscle tendons form a latticework along the neural and haemal spines on the tail, presumably for support. Tendon A tendon or sinew is a tough band of fibrous connective tissue that usually connects muscle to bone and is capable of withstanding tension. Tendons are similar to ligaments; both are made of collagen. Ligaments join one bone to bone, while tendons connect muscle to bone for a proper functioning of the body. Histologically, tendons consist of dense regular connective tissue fascicles encased in dense irregular connective tissue sheaths. Normal healthy tendons are composed mostly of parallel arrays
Quadriceps tendon rupture year. Quadriceps tendon rupture A quadriceps tendon rupture is a tear of the tendon that runs from the quadriceps muscle to the top of the knee cap. Symptoms are pain and the inability to extend the knee against resistance. A gap can often be palpated at the tendon's normal location. The diagnosis is usually made clinically, but ultrasound or MRI can be used if there is any doubt. The tendon can be surgically repaired. Afterwards a brace is given that prevents flexion of the knee. Athletes who have suffered this injury generally return to action in about 9 months to
