They originate at the ilium (upper part of the pelvis, or hipbone) and femur (thighbone), come together in a tendon surrounding the patella (kneecap), and insert at (are attached to) the tibia (shinbone).
What is the origin of the vastus medialis?
Vastus medialis is one of the four muscles that make up the quadriceps group of muscles. It originates from the upper part of the femoral shaft and inserts as a flattened tendon into the quadriceps femoris tendon, which inserts into the upper border of the patella.

What is the function of the rectus femoris?The rectus femoris is located superficially on the middle of the anterior thigh extending between ilium and patella. It is a central muscle of the quadriceps femoris extensor muscles group and acts to extend the leg at the knee.
Article first time published onWhat is the function of the rectus femoris quizlet?
A muscle in the quadriceps, the rectus femoris muscle is attached to the hip and helps to extend or raise the knee. This muscle is also used to flex the thigh. The rectus femoris is the only muscle that can flex the hip.

What is the origin of the gracilis?
Origin. The gracilis muscle originates from the inferior ischiopubic ramus, and body of pubis.
Where are the rectus abdominis located?
A rectus abdominis muscle runs longitudinally along the ventral aspect of the body wall between the pectoral and pelvic girdles, and laterally this muscle is associated with the third group, the lateral hypaxial muscles.

What is the rectus abdominis insertion?
The rectus abdominis muscle inserts onto the costal cartilage of the fifth through seventh ribs. The costal cartilage is shown in this picture as the gray extensions at the front ends of the ribs.
What is the origin of the Sartorius muscle?
The origin for the sartorius is the anterior superior iliac spine, sharing this origin with the tensor fascia lata. At the hip, it acts to both flex the hip as well as externally rotate.
What is the semitendinosus muscle?
The semitendinosus muscle is a member of the posterior component of the thigh which also includes the biceps femoris and the semimembranosus muscles.
What are the 3 hamstring muscles?
- Semitendinosus.
- Semimembranosus.
- Biceps femoris.
Where does the soleus originate and insert?

Where are the hamstring muscles located?
Three muscles run down the back of your leg, from your thigh to your knee — the biceps femoris, semitendinosus, and semimembranosus — and help you bend your knee and extend your hip. As a group, they are known as the hamstring.
Why is the rectus femoris the only muscle of the quadriceps femoris group to have an action on the hip joint?
Because the rectus femoris attaches to the ilium, it is also a flexor of the hip. This action is also crucial to walking or running, as it swings the leg forward into the ensuing step. The quadriceps, specifically the vastus medialis, play the important role of stabilizing the patella and the knee joint during gait.
What is the rectus femoris muscle?
Function: The rectus femoris flexes the hip along with the sartorius and iliopsoas and extends the lower leg at the knee, working in conjunction with the other three quadriceps muscles. The rectus femoris muscle antagonizes the hamstring muscles at the knee and the hip.
Which of the following muscles is named for its origin and insertion?
One muscle that’s named for its origin and insert points is the sternocleidomastoid, which originates at the sternum and clavicle – in this case, ‘cleido-‘ means ‘clavicle’ – and inserts on the mastoid process of the temporal bone.
What does femoris mean in anatomy?
a Latin word meaning “femur” (= the long bone in the upper part of the leg), used in medical names and descriptions.
What three muscles originate from the ischial tuberosity?
They include the semimembranosus, semitendinosus, and the biceps femoris (short and long heads). With the exception of the short head of the biceps femoris, these muscles originate from the ischial tuberosity. The ischial tuberosities can be felt in the center of each buttock and are the bones you sit on.
Which muscle has one of its origins on the ischial tuberosity?
Origin(Posteromedial impression of) Ischial tuberosityActionHip joint: Thigh extension, thigh internal rotation, stabilizes pelvis. Knee joint: Leg flexion, leg internal rotation.InnervationTibial division of sciatic nerve (L5-S2)
Where are the origins of most of the muscles that move the fingers?
Most of the muscles that move the hand originate in the forearm and operate the fingers via their long tendons. Which of the following is NOT a rotator cuff muscle? Teres major is not one of the four rotator cuff muscles, which include supraspinatus, infraspinatus, teres minor, and subscapularis.
What exercise works the rectus femoris?
A simple way to strengthen rectus femoris is to do slow straight leg raises. Simply lay on your back, bend one knee and place that foot on the floor, keep the other leg straight and very slowly lift the leg until both knees meet, hold for a few seconds then slowly lower your leg.
