Biomechanics Quiz 6 True/False

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

False

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

False

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

False

The semimembranosus inserts anteromedially on the medial tibial condyle.

False

The structural instability of the acetabulofemoral joint makes this joint susceptible to subluxations and dislocations.

False

With the exception of the glenohumeral joint, the acetabulofemoral joint is the least mobile joint of the body.

False

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

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.

True

The patellar tendon serves as the insertion point for all of the quadriceps muscles.

True

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