All four of its components are capable to extend the knee, however, they do so in different directions. The main dominant blood supply is the descending branch of the lateral femoral circumflex artery. The muscle descends through the lateral part of the anterior thigh compartment and inserts to the base of patella via the quadriceps tendon. The VL is identified once the dissection has been carried through the fascia lata. From its origin, the vastus lateralis courses down your lateral thigh and inserts as part of the lateral quadriceps tendon on the tibal tubercle. It is located in the anterior compartment of the thigh, together with the sartorius. Vastus intermedius sec.----- it will stop contracting ------resulting - Similar to isotonic . The intervals are between the femoral nerve and the sciatic nerves. Vastus lateralis: linea aspera, greater trochanter of femur. These two muscles work together to maintain the appropriate position of your patella (kneecap) in the femoral groove of your thigh bone. adductor longus BS: ____ a . Some of its tendinous fibers continue downwards and insert into the medial condyle of tibia. Last reviewed: July 22, 2022 (All day) 24.

Along with other muscles of the quadriceps femoris, the vastus lateralis inserts on the tibial tuberosity via the patellar ligament. The tendon of quadriceps continues distally and blends with the patellar ligament which attaches to the tibial tuberosity. The descending branch is in the plane between the VI and the VL and is often encountered during the anterolateral approach to the thigh. The muscle descends over the anterior surface of femur, filling the interval between vastus medialis and lateralis. Lastly, as part of the quadriceps muscle group, the VL eccentrically contracts during downhill walking and descending steps. Nerve Supply. Origin points include the intertrochanteric line, greater trochanter, lateral aspect of the linea aspera, gluteal tuberosity, and the lateral intermuscular septum. The tendon of semimembranosus appears at the level of the mid-thigh and continues caudally toward the point of insertion at the medial condyle of the tibia. The VLL typically inserts at an angle between 10 degrees and 17 degrees +/- 8 degrees. All the contents of the anterior compartment of the thigh lie deep to rectus femoris. The superior gluteal artery is a terminal branch of the internal iliac artery. Larger named veins in the area that assist with drainage are named akin to the corresponding artery. The function of the quadriceps femoris muscle is to extend the leg at the knee joint and to flex the thigh at the hip joint. 2023 Bobby Menges Memorial HSS Limb Reconstruction Course.

The vastus lateralis muscle was separated sharply from the vastus intermedius and rectus femoris muscles, and the distal attachment of the lateral quadriceps expansion, the synovial membrane, and the anterior of . Femoral 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. Copyright As part of the quadriceps muscle group, the VL contracts during the termination of the swing phase of gait to prepare the knee for weight-bearing, the muscle group as a wholeis responsible for absorbing the vast majority of the force generated by the heel strike. Vastus lateralis receives its blood supply from three sources; The vastus intermedius muscle lies between vastus lateralis and vastus medialis. Semimembranosus is a relatively large muscle that originates from a small facet on the rough superolateral surface of the ischial tuberosity. The vastus lateralis originates from the greater trochanter, upper part of the intertrochanteric line, superior aspect of the lateral lip of the linea aspera and gluteal tuberosity of the femur. Last year, the Red Cross saw a 34 percent decline in new donors and a 10 . However, the remaining muscles originate from femur, meaning that their pull is oriented both proximally and laterally. The stretch causes activation of a reflex arc, which cause the quadriceps femoris muscles to contract and oppose the stretch of the tendon. In this study, the vastus lateralis muscles of 15 adult formalin-fixed cadavers (30 cases) were dissected. The vastus lateralis receives arterial blood supply from the ascending, transverse and descending branches of the lateral circumflex femoral artery and perforating branches of the deep femoral artery. Gross anatomy. Clinical anatomy of the quadriceps femoris and extensor apparatus of the knee. Occasionally, the rectus femoris can have a third head that originates from the iliofemoral ligament.

Rectus femoris covers its anterior surface, while vastus lateralis and medialis lie on its lateral and medial surfaces, respectively. It bears this name because it consists of four individual muscles; rectus femoris, vastus medialis, vastus lateralis, and vastus intermedius. In the direct posterior approach, the interval is between the VL and the biceps femoris (sciatic nerve). The sartorius muscle has long parallel fibers that extend for the whole length of the muscle, running obliquely from lateral to medial down the thigh anterior to the quadriceps, in the same direction as the inguinal ligament and the fibers of the external oblique muscles. It originates from two sites on the ilium; the anterior inferior iliac spine (straight head) and supraacetabular groove (reflected head). When its patellar attachment is fixed, this muscle aids to flex the pelvis anteriorly towards the thigh. The muscle also receives someblood supply from perforating arteries of the deep artery of the thigh, also known as the profunda femoris.
