What is the scientific name for vastus lateralis?
Anatomical terms of muscle. The vastus lateralis (/ˈvæstəs ˌlætəˈreɪlɪs, ˈræ-/), also called the ''vastus externus'' is the largest and most powerful part of the quadriceps femoris, a muscle in the thigh. Together with other muscles of the quadriceps group, it serves to extend the knee joint, moving the lower leg forward.
How is the vastus lateralis suture sutured?
The vastus lateralis muscle is reattached to the deep or middle gluteal muscle. Interrupted mattress sutures are used in repair of the tendon of the superficial gluteal muscle. The fascia lata is sutured to the cranial border of the biceps muscle, followed by the subcutaneous fat and fascia in a second layer.
Where does the vastus lateralis attach to the knee?
It arises from a series of flat, broad tendons attached to the femur, and attaches to the outer border of the patella. It ultimately joins with the other muscles that make up the quadriceps in the quadriceps tendon, which travels over the knee to connect to the tibia. The vastus lateralis is the recommended site...
