How Do You Spell MUSCULUS RECTUS FEMORIS?

1. The musculus rectus femoris, commonly known as the rectus femoris muscle, is one of the main quadriceps muscles located in the anterior compartment of the thigh. As part of the quadriceps muscle group, it is situated in the upper part of the thigh, originating from the anterior inferior iliac spine and the superior acetabulum of the pelvis. It then travels down the femur bone and forms a tendon that merges with the other quadriceps muscles to attach to the patella, commonly referred to as the kneecap. From the patella, the quadriceps tendon continues to the tibial tuberosity, where it becomes the patellar ligament.

   The musculus rectus femoris functions to extend the knee joint and flex the hip joint, making it a biarticular muscle. It plays a significant role in activities such as walking, running, jumping, and climbing stairs. It is specifically involved in movements that require power, control, and stability during knee extension, as well as lifting the leg towards the body (hip flexion). The muscle receives its nerve supply from the femoral nerve, which arises from the lumbar plexus.

   Due to its location and functional significance, the musculus rectus femoris is often subject to strain injuries during activities that involve sudden movements, excessive force, or repetitive use. Proper conditioning, warm-up exercises, and stretching techniques are essential for maintaining its health and preventing potential injuries.

2. Origin, anterior inferior spine of ilium and upper margin of acetabulum; insertion, common tendon of quadriceps femoris.
