Start studying Rectus Femoris. Origin : Anterior Inferior Iliac Spine (AIIS). Derek Moore 0 % Topic. This long, spindle-shaped muscle inserts itself in the base of the patella or kneecap where it attaches via the quadriceps tendon.

The rectus femoris muscle is one of the four quadriceps muscles of the human body.The others are the vastus medialis, the vastus intermedius (deep to the rectus femoris), and the vastus lateralis.All four parts of the quadriceps muscle attach to the patella (knee cap) by the quadriceps tendon. 0. It originates near the hip bone at two distinct areas including the acetabulum and the iliac spine. These are It is the only of the quadriceps group knee muscles which also crosses the hip joint. This muscle mainly helps in performing two major functions. Rectus Femoris Insertion. insertion: quadriceps tendon; action: flexes the thigh at the hip joint and extends the leg at the knee joint; arterial supply: descending branch of the lateral circumflex femoral artery; innervation: femoral nerve; Gross anatomy. ORIGIN Straight head: anterior inferior iliac spine. It is a bulk of muscle located in the superior, anterior middle compartment of the thigh and is the only muscle in the quadriceps group that crosses the hip.. The rectus femoris muscle is the only one that crosses the hip joint and therefore is related to tight hip flexors. Attachments of Rectus Femoris: Origin and Insertion. The rectus femoris can be found smack dab in the middle of the thigh. The insertion also occurs into the tubercle of tibia through Ligamentum Patellae. Rectus femoris is part of the quadriceps group. RECTUS FEMORIS. It runs straight down the leg. Reflected head: ilium above acetabulum: INSERTION Quadriceps tendon to patella , via ligamentum patellae into tubercle of tibia: ACTION Extends leg at knee. It is superior and overlying of the vastus intermedius muscle and superior-medial part of Vastus lateralis and Vastus medialis..
