Vastus medialis lies medial to rectus femoris and is partially covered by it. In the middle third of the thigh, vastus medialis forms the lateral wall of the adductor canal (Hunters canal). The stretch causes activation of a reflex arc, which cause the quadriceps femoris muscles to contract and oppose the stretch of the tendon. The muscle is composed of two muscular bands or fasciculi, which are attached to the upper aspect of the palatine aponeurosis. The superior gluteal artery is a terminal branch of the internal iliac artery. Or jump into a prepared custom quiz about the parts of the quadriceps femoris muscle and add additional muscles to the selection yourself, if needed.

The lateral intermuscular septum is much stronger than the other two and separates the VL and VI of the anterior compartment from the short and long heads of the biceps femoris and the posterior compartment. Thethree branches of this vessel are anatomic landmarks in many orthopedic approaches to the hip. The lateral circumflex femoral and superficial circumflex iliac arteries also contribute to the blood supply of rectus femoris, but to a lesser extent. Due to its extensive originon the femur, the VL plays a key role as a landmark in many operative procedures involving both the femur and the hip joint. Occasionally, the rectus femoris can have a third head that originates from the iliofemoral ligament. The main dominant blood supply is the descending branch of the lateral femoral circumflex artery.

If a superolateral inflow portal is to be used during an arthroscopic knee procedure, the portal is placed lateral to the body of the VLO. The VLO, however, has an insertional variation between 26 degrees and 41 degrees.[5]. The muscle descends through the lateral part of the anterior thigh compartment and inserts to the base of patella via the quadriceps tendon. The tensor fasciae lata is mainly perfused by a deep perforating branch of the superior gluteal artery. [3] A layer of fat or fascia achieves this separation from the longitudinal head in most specimens. It originates from two sites on the ilium; the anterior inferior iliac spine (straight head) and supraacetabular groove (reflected head). The lowermost fibers lie in an almost horizontal plane, forming a noticeable bulge superior to the medial side of the patella. Philadelphia, PA: Lippincott Williams & Wilkins.
