The Hip

Question 1

What muscles are primarily used for flexion the hip?

Answer 1

Psoas, iliacus, rectus femoris, sartorius

Question 2

What muscles are primarily used for extension the hip?

Answer 2

Gluteus maximus and the hamstrings

Question 3

3 Hamstring muscles

Answer 3

biceps femoris, semimembranosis, semitendinosis

Question 4

What muscles are primarily used for abduction?

Answer 4

Gluteus medius, gluteus minimus, tensor fasciae latae

Question 5

What muscles facilitate medial rotation?

Answer 5

Gluteus medius, gluteus minimus, and the tensor fasciae latae

Question 6

This is a long thin muscle running from the inferomedial pubis to the tibial shaft below the medial tibial condyle. Together with the adductor magnus they adduct the hip.

Answer 6

Gracilis

Question 7

Originates near the ASIS and inserts on the iliotibial band and the head of the fibula. It abducts, flexes and medially rotates the thigh.

Answer 7

Tensor fasciae latae

Question 8

Originates at the bodies of T12-L5 and inserts on the lesser trochanter. Primarily it aids in hip flexion, but it also works to support the spine in upright posture.

Answer 8

Psoas Major

Question 9

Originates from the entire internal iliac fossa (fossa is any depressed or hollowed area) and inserts on the lesser trochanter via the same tendon as the psoas major. Primarily it aids in hip flexion. (It also aids in anteversion when the femur is fixed)

Answer 9

Iliacus

Question 10

This is the largest muscle in the body and along with adipose tissue make up the buttocks. It originates from the posteriolateral sacrum and posterior ilium and inserts on the shaft of the femur. It acts primarily as a hip extensor
(Tendu in arabesque) and to laterally rotate the hip (turnout)

Answer 10

Gluteus Maximus

Question 11

Originates at the anterior inferior iliac spine and part of the ilium near the acetabulum and inserts onto the quadriceps tendon. It is superficial to the vasti and unlike the other quadriceps it crosses the hip as well as the knee making it is the only quadriceps muscle that is a primary hip flexor.

Answer 11

Rectus femoris

Question 12

Is the longest muscle in the body with its origin at the ASIS and the insertion superomedial shaft of the tibia. It flexes, abducts and laterally rotates the hip.
In dance we call the Sartorius the posse muscle. It is often called the Tailor muscle (as tailors would sit cross legged on the floor in past history) because it flexes, abducts and laterally rotates the hip.
The three hamstring muscles are: semimembranosis, semitendinosis, biceps femoris

Answer 12

Sartorius

Question 13

What muscles facilitate lateral rotation?

Answer 13

Gluteus maximus, piriformis, obturator
