KIN 3304- Chapter 9 Questions

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

Bursae are composed mainly of fatty tissue

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

Gerdy's tubercle

Which of the following is true regarding the medial collateral ligament?

Maintains medial stability by resisting valgus forces or preventing tibia from being abducted

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

Provides static stability to the knee joint

Which of the following represents the truest agonistic relationship for the knee?

Semitendinosus and semimembranosus in internal rotation

Which of the following is not correct regarding the knee joint proper?

Sometimes referred to as trochoginglymus joint due to internal and external rotation occurring when in full extension

Which of the following is not true regarding strength and endurance being essential for maintenance of patellofemoral stability?

Strength and flexibility are not often a problem with the muscles of the knee joint

The sartorius, gracilis, and semitendinosus muscles all insert just below the medial condyle on the upper anteromedial tibial surface and assists with knee internal rotation.

false

The semimembranosus muscle inserts anteromedially on the medial tibial condyle and assists with knee internal rotation.

false

All three of the vasti muscles of the quadriceps originate on the proximal femur and insert on the patellar superior pole.

true

The biceps femoris muscle inserts primarily on the head of the fibula and assists with knee external rotation.

true

The lateral fibula serves as the attachment for knee joint structures but does not articulate with the femur or patella.

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

true

Which of the following is not true regarding the rectus femoris, vastus medialis, vastus intermedius, vastus lateralis?

All are superficial and palpable except vastus medialis

The Q angle is usually _____ or less for males and _____ or less for females.

15; 20

The rectus femoris is more powerful in extending the knee when the hip is in _____.

extension

Which of the following is correct regarding the patellofemoral joint?

Part of the posterior patella is superior to the trochlea groove when the knee is in full extension.

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

The lateral meniscus is larger in circumference than the media

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

They all extend the knee and flex the hip when contracting concentrically

In basketball and soccer injury to the _____ occurs much more commonly to females than to males.

anterior cruciate ligament

The most common serious knee ligament injury involves the _____.

anterior cruciate ligament

As the knee approaches full extension the tibia must internally rotate approximately 10 degrees to achieve proper alignment of the tibial and femoral condyles.

false

The anterior and posterior cruciate ligaments are located on the outermost anterior and posterior surfaces of the knee joint.

false

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

false

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

false

The lateral collateral ligament is more frequently injured than other knee joint ligaments.

false

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

false

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

false

The popliteus muscle originates on the medial aspect of the lateral femoral condyle and assists with knee internal rotation.

false

The semimembranosus muscle is located posteromedially and internally rotates the knee and is directly antagonist to the vastus lateralis in all of its actions.

false

The semitendinosus muscle is located posterolaterally and internally rotates the knee.

false

The only uniarticular knee flexor is the _____.

popliteus

Which of the following is not true with respect to the synovial cavity?

provides the knee with stability

Which of the following muscles internally rotates the knee when contracting concentrically?

semimembranosus

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

superolateral

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

superomedial

Which of the following muscles is important in providing dynamic medial stability to the knee joint because of the manner in which it crosses the joint and is also responsible for internal rotation of the knee?

the semimembranosus muscle

Articular cartilage is located on the surfaces of the femur, tibia and patella.

true

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

true

The iliotibial tract of the tensor fasciae latae muscle inserts on Gerdy's condyle.

true

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

true

The knee joint is the largest joint in the body.

true

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

true

The quadriceps muscles perform eccentric contractions before concentric contractions in explosive jumping.

true

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

vastus medius
