femur
The primary movements of the biceps femoris at the knee joint include ___________________, and external rotation.
flexion
When the semitendinosus contracts, the resultant movement to the knee joint is____________________ , and internal rotation.
flexion
Rotary movement of the lower leg medially toward the midline is termed ________________
internal rotation
The _____________ joint is the largest diarthrodial joint in the body.
knee
The only uniarticular knee flexor is the _____. Biceps femoris Popliteus Semimembranosus Vastus intermedius
popliteus
Which of the following is not true regarding the hamstring muscle group? Responsible for knee flexion Located in posterior compartment of thigh Consists of 3 separate muscles Provides static stability to the knee joint
provides static stability to the knee joint
Which of the following is not considered to be one of the quadriceps muscle group? Rectus femoris Vastus lateralis Vastus intermedius Semitendinosus
semitendinosus
The vastus lateralis provides a _____ pull on the patella when contracting concentrically. inferolateral superior superolateral superomedial
superolateral
The vastus medialis provides a _____ pull on the patella when contracting concentrically. inferolateral superior superolateral superomedial
superomedial
The vastus medialis provides a _____ pull on the patella when contracting concentrically. inferomedial superior superolateral superomedial
superomedial
The vastus medialis has the following origin: whole length of the _______________________ and medial condyloid ridge.
linea aspera
The semimembranosus has the following insertion: posteriomedial surface of the ____________ tibial condyle.
medial
The vastus intermedius has the following insertion: upper border of the ________________ and patellar tendon to tibial tuberosity.
patella
Articular cartilage is located on the surfaces of both the femur and tibia. T F
T
The lateral fibula serves as the attachment for knee joint structures but does not articulate with the femur or patella. T F
T
The medial collateral ligament originates on the medial aspect of upper medial femoral condyle and inserts on medial tibial surface. T F
T
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. T F
T
The sartorius, gracilis, and semitendinosus all insert just below the medial condyle on upper anteromedial tibial surface. T F
T
The semimembranosus inserts anteromedially on the medial tibial condyle. T F
T
The semimembranosus is located posteromedially and internally rotates the knee. T F
T
Muscles that flex the knee include all of the following except? Biceps femoris Tensor fascia latae Sartorius Gracilis
Tensor fascia latae
