Answer 4

No q

Question 5

Articulation in knee joint

Answer 5

: 2 tibiofemoral - between medial and lateral condyles of femor and tibia
: 1 femoropatellar - between patella and femor

Question 6

Ligaments of knee joint

Answer 6

Fibular collateral ligament
Tibial collateral ligament
Oblique popliteus ligament 
Arcuate popliteal ligament 
Cruciate ligament - ant and post 
Meniscus - medial and lateral

Question 7

Attachment of fibular collateral ligament

Answer 7

From lateral epicondyle of femor to lateral surface of fibular head

Question 8

Function of fibular collateral ligament

Answer 8

Keep the knee stable

Question 9

Tibial collateral ligament attachment

Answer 9

Medial condyle of femor to medial condyle and superior part of medial surface of tibia

Question 10

Oblique collateral ligament attachments.

Answer 10

• Expansion of semi membranosus tendon
• Originates from post side of medial condyle of tibia
• And attach to lateral femoral condyle
• supports and blends with central part of joint capsule as it pass over intercondylar fossa

Question 11

Arcuate popliteal ligament attachments

Answer 11

• Originates from posterior aspect of fibular head

- And spread over post surface of knee joint

Question 12

Popliteal ligament functions ( both oblique and arcuate )

Answer 12

Prevent overextenion of knee joint

Question 13

Anterior cruciate ligament attachments

Answer 13

• originates from medial wall of lateral femoral condyle posteriorly
• inserts into anterior of intercondylar area

Question 14

Function of anterior cruciate ligament

Answer 14

• prevent rolling and sliding of tibia in front of femur

- prevent hyperextension of knee joint

Question 15

Posterior cruciate ligament attachments

Answer 15

• Originates from post intercondylar area of tibia

- attach to lateral surface of medial condyle of femur anteriorly

Question 16

Function of posterior cruciate ligament

Answer 16

• prevent hyperflexion of knee joint

Question 17

What are menisci

Answer 17

• fibrocartilaginous moon shaped plates

- these are present on articular surface of tibia

Question 18

Function of menisci

Answer 18

• shock absorption

- provide cushion to knee

3 anserine 
4 gastrocnemius 
5 semi membranosus
6 sub cutaneous pre patellar
7 sub cutaneous infra patellar
8 deep infrapatellar

Question 20

Suprapattelar location

Answer 20

Between femor and tendon of quadricep femoris
