When sitting which of the following movements would most likely result in the process of attempting to flex the right hip?

Posterior pelvic rotation

Muscles that flex the knee include all of the following except

Tensor fascia latae

The most common serious knee ligament injury involves the ____

acl

The hamstring muscles function as a decelerator of the knee when decreasing speed to change direction and especially when landing from a jump.

false

Which of the following is not true regarding the hamstring muscle group?

Provides static stability to the knee joint

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

true

The knee joint can extend to 180 degrees normally although some individuals can extend slightly further.

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

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

false

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

flexion

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

laterally; abduction

The biceps femoris muscle is located _____ and performs _____ of the hip joint.

posteriorly; extension

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

superior

The vastus lateralis provides a _____ pull on the patella when contracting concentrically.

superolateral

Tears in menisci can occur due both compression and shear forces during rotation while flexing or extending during quick directional changes in running.

true

The medial collateral ligament originates on the medial aspect of upper medial femoral condyle and inserts on medial tibial surface.

true

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

true

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

true

Which of the following is not correct regarding menisci in the knee joint?

Decreases stability

All of the following are key bony landmarks for knee joint actions except:

Gerdy's condyle

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

Gluteus maximus

Which of the following is not considered to be one of the quadriceps muscle group?

Vastus medius

Which of the following is correct regarding the patellofemoral joint?

Classified as an arthrodial type joint

Which of the following is not true regarding the bursae of the knee?

Bursae are composed mainly of fatty tissue

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

Rich nervous innervation

The iliopsoas muscle is located _____ and performs _____ of the hip joint.

anteriorly; flexion

The vastus medialis provides a _____ pull on the patella when contracting concentrically.

superomedial

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

true

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

true

Agonist muscles during hip flexion include all of the following except:

Adductor magnus
