External rotation

Due to the adductor brevis, adductor longus, and adductor magnus all inserting in various locations on the linea aspera, a resulting movement that is facilitated when adducting the hip is ______. ?

False

Hip flexion is movement of the femur straight posteriorly toward the pelvis. (T/F)

Sartorius

Agonist muscles during hip extension include all of the following except the?

True

Any muscle that is agonistic in hip extension can also contract to cause anterior pelvic rotation. (T/F)

False

The acetabulum inserts into the femoral head to form the acetabular femoral joint. (T/F)

Posteriorly, extension

The biceps femoris muscle is located ________ and performs _______ of the hip joint. ?

b. Laterally, abduction

The gluteus medius muscle is located ________ and performs ________ of the hip joint.

False

The iliofemoral or Y ligament is located posteriorly and prevents hyperextension. (T/F)

Anteriorly, flexion

The iliopsoas muscle is located ______ and performs _______ of the hip joint. ?

Semimembranosus

The insertion of the _________ muscle is the posteromedial surface of the medial tibial condyle. ?

Iliopectineal

The insertion of the iliopsoas muscle is the pectineal line and the _____ eminence, lesser trochanter of the femur, and the shaft just below. ?

a. Superior

The insertion of the rectus femoris muscle is the _______ aspect of the patella and the patellar tendon to the tibial tuberosity.

Anterolateral

The insertion of the tensor fasciae latae muscle is one-fourth of the way down the thigh into the iliotibial tract, which inserts onto Gerdy's tubercle of the ______ tibial condyle.

Iliopsoas

The origin of the _______ muscle is the lower borders of the transverse processes of lumbar vertebrae (L1-L5), inner surface of the ilium, sides of the bodies of the last thoracic vertebra (T12), all the lumbar vertebrae (L1-5), intervertebral fibrocartilages, and base of sacrum. ?

Coccyx

The origin of the gluteus maximus muscle is the posterior one-fourth of the crest of the ilium, posterior surface of the sacrum and ________ near the ilium, and fascia of the lumbar area.

Acetabulum

The origin of the rectus femoris muscle is the anterior inferior iliac spine and the groove (posterior) above the _____. ?

Iliac crest

The origin of the tensor fasciae latae muscle is the anterior _______ and the surface of the ilium just below the crest.

True

The patella serves as a pulley by improving the angle of pull with the result being a greater mechanical advantage for the quadriceps during knee extension (T/F)

Extension

The rectus femoris is more effective in hip flexion when the knee is in _________. ?

Anteriorly, flexion

The sartorius muscle is located _________ and performs _________ of the hip joint.

True

The sartorius, gracilis, and semitendinosus all insert just below the medial condyle on upper anteromedial tibial surface. (T/F)

False

The semimembranosus inserts anteromedially on the medial tibial condyle. (T/F)

False

The teres ligament is located superficially and slightly limits adduction. (T/F)

False

The teres ligament is located superficially and slightly limits adduction. ?

Rich nervous innervation

Which of the following does not contribute to the relative stability of the acetabular femoral joint? ?

Gluteus maximus

Which of the following is considered to be an agonist muscle during hip external rotation?

a. Abduction of the hip

Which of the following is not an action of the pectineus muscle?

True

For the pelvis to rotate a significant amount motion must occur in either the right hip, the left hip, the lumbar spine or some combination of these joints. (T/F)

External

If desiring to emphasize work on the gluteus maximus during resisted hip extension exercises, the knee should be placed in _________. ?
