False

In the context of the pelvic girdle motions, anterior pelvic rotation refers to the anterior movement of the upper pelvis in which the iliac crest tilts forward in the transverse plane. True False

False

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

False

The acetabulum inserts onto the femoral head to form the acetabular femoral joint. True False

False

The femoral condyles articulate with the fibular condyles during flexion of the knee. True False

False

The lateral collateral ligament originates on the lateral femoral condyle distally to the popliteus muscle origin and inserts on the fibular head. True False

False

The patella is classified as an "irregular" bone because it is imbedded in the patellar tendon. True False

False

The structural instability of the acetabular femoral joint makes it susceptible to subluxations and dislocations. True False

False

The teres ligament is located anteromedially and inferiorly and slightly limits adduction. True False

False

Anteriorly, the pelvic bones are joined to form the symphysis pubis, an amphiarthrodial joint. True False

True

Articular cartilage is located on the surfaces of both the femur and tibia. True False

True

For the pelvis to rotate in any direction, movement must occur in either the right hip, the left hip, the lumbar spine, or a combination of these locations. True False

True

The fibula is not part of the ginglymus articulation of the knee joint. True False

True

The knee joint is the largest joint in the body. True False

True

The pelvic girdle consists of a right and left pelvic bone joined together posteriorly by the sacrum. True False

True

The tibia bears the majority of the weight as compared to the fibula. True False

True
