Rectus Femoris Muscle

Rectus femoris muscle

The Rectus Femoris Muscle is one of the four quadriceps muscles of the human body. The others are the vastus lateralis, vastus medialis, and vastus intermedius. It is located in the middle of the front of the thigh.

Structure[edit | edit source]

The rectus femoris muscle arises from the iliac spine and the acetabular rim. From there, it descends down the thigh, and its fibers end in a common tendon with the other quadriceps muscles, which attaches to the patella and then to the tibia via the patellar ligament.

Function[edit | edit source]

The rectus femoris is a key muscle in the knee extension and hip flexion. It is also involved in maintaining the upright posture and walking and running.

Clinical significance[edit | edit source]

Injury to the rectus femoris muscle, such as a strain or tear, can cause pain, swelling, and reduced function. Treatment may include rest, ice, compression, and elevation (RICE) and physical therapy.
