Quad muscle anatomy

The vastus lateralis originates on the lateral surface of the femur, the vastus intermedius on the anterior surface, and the vastus medialis on the medial surface. All four quads insert on the patella (the kneecap) via the quadriceps tendon and on the tibial tuberosity via the patellar ligament. The quadriceps femoris is a group of muscles located in the front of the thigh.

Each of the vastus muscles originates on. Your quads are made up four muscles , all of which help straighten your knee: the rectus femoris, the vastus lateralis, the vastus medialis, and the vastus intermedius.

Anatomy of the Quad Muscles. Quadriceps muscles Dr Henry Knipe and Dr Craig Hacking et al. The vastus lateralis muscle originates at the linea aspera and greater trochanter of the femur, loops around the shaft and mainly runs into the quadriceps tendon.

Mirror-inverted to the vastus medialis muscle a small part goes around the patella laterally and inserts at the lateral condyle of the tibia (lateral patellar retinaculum). Vastus intermedius – vastus. It has four parts: rectus femoris , vastus lateralis , vastus medialis , and vastus intermedius.

It is the great extensor muscle of the knee, forming a large fleshy mass which covers the front and sides of the femur.

There are three major muscles in the anterior thigh – the pectineus, sartorius and quadriceps femoris. Ebraheim’s educational animated video describes the anatomy of the quadriceps muscle group. The muscles are located: superficial: rectus femoris. The primary function of this muscle is to perform knee flexion. Normal anatomy of the quadriceps muscle ( Figs.

1–3) The tendon is composed of multiple laminae positioned one on top of the other. The superficial lamina is continuous with the muscle fibers of the RF. The intermediate lamina receives the fibers of the VM and VL, and the deepest lamina receives the fibers of the VI. Start studying anatomy quadriceps muscles. Learn vocabulary, terms, and more with flashcards, games, and other study tools.

Whether you hit the hardwoo the gridiron or the baseball diamon a quadriceps strain can hit you. A thigh strain or quadriceps strain is a tear in one of the quadriceps muscles at the front of the thigh. It is common in sprinting and jumping related sports. Our thigh strain treatment and rehabilitation program includes sports massage, stretching, strengthening and sports specific exercises. Of the quadriceps muscles, it has the least affect on flexion of the knee.

The hamstrings are three muscles at the back of the thigh that affect hip and knee movement.

As indicated by its name, it is actually composed of four muscles: the rectus femoris, vastus medialis, vastus lateralis and vastus intermedialis. A systematic review resulted in a frequency from to of all football injuries were categorized as contusion, strains or sprains. The injury is caused by a sudden force to the quadriceps muscle causing significant muscle damage. For mild tears, after the pain and swelling have subside you can begin light exercise to prevent stiffness and regain mobility and strength in your injured quad. Usually this is about five days after the strain occurred.

A few times a day, gently stretch the quadriceps muscle. The rectus femoris originates at the ilium, thus crossing both the hip and knee joint along its course. This anatomy allows for hip flexion and knee extension. The Quads are a large muscle group on the front of your thigh. They are divided into several heads: the rectus femoris, the vastus lateralis, the vastus medialis and the vastus intermedius.

A little quadriceps anatomy. Your quadriceps “muscle” is actually a group of three large muscles and one smaller one that merge just above the knee.
