Rectus Femoris Anatomy App As part of the quadriceps, the rectus femoris is one of the primary muscles that extend the leg at the knee joint. additionally, it works alongside the ilipsoas and sartorius muscles to flex the thigh at the hip joint. One head originates from the anterior inferior iliac spine and other from the supra acetabular groove (of the ilium). the two heads converge into one tendon which inserts onto the patella via the quadriceps femoris tendon. the patella is then attached to the tibial tuberosity by the patella ligament.
Rectus Femoris Anatomy Origin Insertion Action In 2025 The Originals Quick facts origin: anterior inferior iliac spine and supraacetabular groove of ilium. insertion: tibial tuberosity, via tendon of quadriceps femoris muscle and patellar ligament. action: extends leg at knee joint; flexes thigh at hip joint. innervation: femoral nerve (l2 l4). arterial supply: deep femoral and lateral circumflex femoral arteries. Rectus femoris can be palpated as it is the most superior of the quadriceps muscles. start palpation at aiis, rectus femoris can be felt until its insertion into the quadriceps tendon. Interactive 3d model of the rectus femoris muscle and information on its origin, insertion, action, innervation, and blood supply. By rainey lynd upper leg anatomy rectus femoris muscle origin: anterior inferior iliac spine, supraacetabular groove insertion: tibial tuberosity (via patellar ligament), patella actions: extension of the leg at the knee innervation: posterior division of the femoral nerve (l3, l4) blood supply: femoral artery and branches from the profunda.

Out of all four muscles, only the rectus femoris crosses both the hip and knee joints. the others cross only the knee joint. these muscles differ in their origin, but share a common quadriceps femoris tendon which inserts into the patella. The rectus femoris is one of the four muscles that make up the quadriceps femoris group. it is unique among the quads because it is the only one that crosses two joints (the hip and the knee). The rectus femoris is one of the four quadriceps femoris muscles located in the anterior compartment of the thigh. it is the only quadriceps muscle that crosses both the hip and knee joints, enabling it to flex the hip and extend the knee. Its functions are to flex the thigh at the hip joint and to extend the leg at the knee joint. [1] it arises by two tendons: one, the anterior or straight, from the anterior inferior iliac spine; the other, the posterior or reflected, from a groove above the rim of the acetabulum.
