Bursae are composed mainly of fatty tissue.
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 quadriceps muscle group?
Covered by the vastus fascia
Muscles that flex the knee include all of the following except:
tensor fascia latae.
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, and vastus lateralis?
All are superficial and palpable, except the vastus medialis.
Which of the following is not correct regarding menisci in the knee joint?
Decreases stability
Which of the following muscles internally rotates the knee?
Semimembranosus
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 only uniarticular knee flexor is the _____.
popliteus
All the three vasti muscles of the quadriceps originate on the proximal femur and insert on the patellar superior pole.
true
The knee joint is the largest joint in the body.
true
Which of the following is not true regarding the hamstring muscle group?
Provides static stability to the knee joint
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.
Which of the following is not considered to be one of the quadriceps muscle group?
Vastus medius
The most common serious knee ligament injury involves the _____.
anterior cruciate ligament
Which of the following is not true with respect to the synovial cavity?
Provides the knee with stability
The popliteus muscle originates on the medial aspect of the lateral femoral condyle.
false
The quadriceps muscles perform eccentric contractions during accelerating actions.
false
The semimembranosus muscle inserts anteromedially on the medial tibial condyle.
false
The semitendinosus muscle is located laterally and internally rotates the knee.
false
Which of the following muscles externally rotates the knee?
Biceps femoris
The rectus femoris is more powerful in extending the knee when the hip is in _____.
extension
The pes anserinus tendinous expansion comprises the _____.
gracilis, sartorius, and semitendinosus
The sartorius, gracilis, and semitendinosus muscles all insert just below the medial condyle on the upper anteromedial tibial surface.
true
Which of the following is not correct regarding the knee joint proper?
Sometimes referred to as a trochoginglymus joint because of internal and external rotation occurring when in full extension
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 biceps femoris muscle inserts primarily on the head of the fibula.
true
The fibula is not part of the ginglymus articulation of the knee joint.
true
The iliotibial tract of the tensor fasciae latae muscle inserts on Gerdy's tubercle.
true
The knee joint can extend to 180 degrees normally, although some individuals can extend slightly further.
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 semimembranosus muscle is located posteromedially and internally rotates the knee.
true
All of the following are key bony landmarks for knee joint actions except:
Gerdy's condyle.
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
Articular cartilage is located on the surfaces of both the femur and tibia.
true
As the knee approaches full extension, the tibia must externally rotate approximately 10 degrees to achieve proper alignment of the tibial and femoral condyles.
true
