The Knee

Question 1

3 Bones of the knee

Answer 1

femur, tibia, patella

Question 2

This is the large muscle of the posterior leg, or calf. It originates with two heads on the posteroinferior femur, just above the condyles, and inserts on the calcaneus via the Achilles tendon. It flexes and medially rotates the knee. (It also acts as and ankle extensor or plantar flexor).

Answer 2

Gastrocnemius

Question 3

The lateral aspect of the lateral femoral condyle and inserts in a triangle on the postero-superomedial tibial shaft. It flexes and medially rotates the knee.

Answer 3

Popliteus

Question 4

Originates at the anterior inferior iliac spine and part of the ilium near the acetabulum and inserts onto the quadriceps tendon. It is superficial to the vasti and unlike the other quadriceps it crosses the hip as well as the knee making it a primary hip flexor. We did some work on the mats while working with hip flexion to relax this muscle as it is often tight in dancers.

Answer 4

Rectus femoris

Question 5

This is a strong ligament containing the patella. It originates at the quadriceps tendon inserts on the tibial tuberosity.

Answer 5

Patella Ligament

Question 6

a C-shaped disc of fibrocartilage encircling the tibial condyle. Aids in the distribution synovial fluid and help provide a broader base to the tibial condyles thereby spreading the distribution of weight. This helps reduce pressure on the joint.

Answer 6

Meniscus

Question 7

3 muscles that flex the knee

Answer 7

popliteus, gastrocnemius, hamstrings (semitendinosis, semimembranosis, biceps femoris)

Question 8

4 specific quadriceps muscles responsible for extension of the knee

Answer 8

Vastus lateralis, vastus medialis, rectus femoris, vastus intermedialis

Question 9

5 ligaments of the knee

Answer 9

Interior cruciate ligament, anterior cruciate ligament, lateral cruciate ligament, medial cruciate ligament, patella ligament
