The rectus femoris tendon can cause a fragment of anterior inferior iliac spine of the hip to avulse in what is known as an avulsion fracture. This is due to forceful contraction of the muscle that generates a force greater than that which holds the bone together. This is a well recognized, but unusual sports injury that can affect young ...
The quadriceps muscles consist of the rectus femoris, vastus lateralis, vastus medialis, and vastus intermedius. These quadriceps muscles are innervated by the femoral nerve. [ 1 ] The tibial tuberosity thus forms the terminal part of the large structure that acts as a lever to extend the knee-joint and prevents the knee from collapsing when ...
The vastus medialis muscle is on the medial side of the femur (i.e. on the inner part thigh). [1] The vastus intermedius muscle lies between vastus lateralis and vastus medialis on the front of the femur (i.e. on the top or front of the thigh), but deep to the rectus femoris muscle. Typically, it cannot be seen without dissection of the rectus ...
The vastus lateralis is the largest and most powerful of the three vasti muscles. It arises from the several areas of the femur, including the upper part of the intertrochanteric line; the lower, anterior borders of the greater trochanter, to the outer border of the gluteal tuberosity, and the upper half of the outer border of the linea aspera.
Rectus femoris is attached to the pelvis with two tendons, while the vasti are inserted to the femur. All four muscles unite in a common tendon inserted into the patella from where the patellar ligament extends it down to the tibial tuberosity .
Muscle architecture is the ... This is largely due to the different lengths and varying insertion points of the muscle fibers. ... as well as the rectus femoris of ...
A tendon connects muscle to bone, while a ligament connects bone to bone. [1] Injuries are common to this tendon, with tears, either partial or complete, being the most common. If the quadriceps tendon is completely torn, surgery will be required to regain function of the knee. [2] Without the quadriceps tendon, the knee cannot extend.
Due to being the deeper middle-most of the quadriceps muscle group, the intermedius is the most difficult to stretch once maximum knee flexion is attained. It cannot be further stretched by hip extension as the rectus femoris can, nor is it accessible to manipulate with massage therapy to stretch the fibres sideways as the vastus lateralis and ...
