Rectus Femoris Muscle
Rectus Femoris Muscle is located in the middle of front Thigh. It has a fusiform shape and its fibers are arranged in Bipenniform manner. The muscle is raised by two tendons which are as follows. Anterior or Straight: from Anterior Inferior Iliac Spine Posterior or Reflected: from above the rim of Acetabulum
The blood supply to the Rectus Femoris Muscle from proximal to distal end is provided through the deep Femoral Artery, which is the descending branch of Lateral Circumflex Artery.
The nerve supply to the muscle is provided by the branches of Femoral Nerve L2, L3 and L4.
All the Quadriceps Muscles are responsible for the extension of Knee but the Rectus Femoris muscles also joins with Acetabulofemoral Joint (Hip joint) and Anterior Inferior Iliac Spine. These joints allow the Rectus Femoris Muscle to assist in Flexion of Hip.
Muscle overuse in kicking or sprinting may injure the muscle. The physical exercise of this muscle may cause pain in the Groin. Rectus Femoris Strain is also known as Hip Flexor Strain, an injury at the tendon that attaches to the Patella. The injury is commonly a partial tear or could be a full one. Symptoms of it include sharp pain at hip or in groin, swelling, bruising and inability to contract the muscle.
