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

C. flexion

6. The acetabulum inserts into the femoral head to form the acetabular femoral joint.

Falce; The femoral head inserts into the acetabulum to form the acetabular femoral joint

1. The tibial tuberosity serves as the insertion point for all of the quadriceps muscles.

False, The tibial tuberosity serves as the insertion point for all of the quadriceps muscles.

16. Anterior pelvic rotation is anterior movement of the upper pelvis where the iliac crest tilts forward in the transverse plane.

False; Anterior pelvic rotation is anterior movement of the upper pelvis where the iliac crest tilts forward in the sagittal plane.

15. Hip flexion is movement of the femur straight posteriorly toward the pelvis.

False; Hip flexion is movement of the femur straight anteriorly toward the pelvis.

9. The structural instability of the acetabular femoral joint makes this joint susceptible to subluxations and dislocations.

False

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

False; The teres ligament is located deep and slightly limits adduction.

10. The iliofemoral or Y ligament is located posteriorly and prevents hyperextension.

True

13. The obturator nerve innervates both the adductor longus and gracilis muscles.

True

7. The acetabular femoral joint is reinforced by an extremely weak ligamentous capsule and the stability of this joint is attributed to the surrounding musculature.

False; The acetabular femoral joint is reinforced by an extremely strong ligamentous capsule and the stability of this joint.

8. The tibial nerve innervates both the gracilis and biceps femoris muscles.

False; The obturator nerve innervates the gracilis, while the tibial nerve innervates biceps femoris long head and peroneal nerve innervates biceps femoris short head. muscles.

11. The pubofemoral ligament is located anteromedially and inferiorly and limits excessive extension and abduction.

False; The pubofemoral ligament is located anteromedially and inferiorly and limits excessive extension and external rotation.

19. The semimembranosus inserts anteromedially on the medial tibial condyle.

False; The semimembranosus inserts posteromedially on the medial tibial condyle

4. With the exception of the glenohumeral joint, the acetabular femoral joint is the least mobile joint of the body.

False; With the exception of the glenohumeral joint, the acetabular femoral joint is the most mobile joint of the body.

20. The three biarticular hamstring muscles are innervated by the tibial division of the sciatic nerve.

True, BUT biceps femoris short head innervated by peroneal

14. The sartorius, gracilis, and semitendinosus all insert just below the medial condyle on upper anteromedial tibial surface.

True

17. Normally, the hip joint can be abducted to approximately 35 degrees.

True

18. Functions of the acetabular femoral joint include weight bearing and locomotion.

True

2. The two pelvic bones join to form the amphiarthrodial joint referred to as the symphysis pubis.

True

21. 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.

True

22. The femoral nerve innervates essentially all of the hip flexor muscles.

True

24. The most palpable point of the femur at the hip is the greater trochanter.

True

25. The right and left pelvis are joined together by the sacrum at the right and left sacroiliac joints.

True

3. The tibial nerve innervates both the semitendinosus and semimembranosus.

True

5. 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.

True
