Question 3

Ligaments outside the stifle joint

Answer 3

5 ligaments

• Retinaculum patellae
• Lig.patellae
• Lig.collaterale laterale
• Lig.collaterale mediale
• Lig.femoropatellare laterale
• Lig.femoropatellare mediale

Question 4

Retinaculum patellae

Answer 4

From fascia latae and aponeurosis om muscles, covers stifle

Question 5

Lig.patellae

Answer 5

Continuation of tendon from m.quadriceps femoris. The patella is a sesamoid bone in the tendon, before the ligament inserts on tub.tibiae

Question 6

Lig.collaterale laterale

Answer 6

From laterale epicondyle of femur to caput fibulare and a lesser part to the lateral condyle of tibia. Underneath there is the tendon om m.popliteus.

Question 7

Lig.collaterale mediale

Answer 7

From medial epicondyle of femur to medial condyle of tibia and a strong attachment to the medial meniscus.

Question 8

Lig.femoropatellare laterale

Answer 8

From lateral Vesalius (sesamoid) bone to patella and also to the lateral epicondyle of femur. Reinforcment of joint´s capsule.

Question 9

Lig.femoropatellare mediale

Answer 9

From medial Vesalius (sesamoid) bone to patellae, and also to the medial epicondyle of femur. Reinforcment of joint´s capsule.

Question 10

Corpus adiposum infrapatellare

Answer 10

Fatty tissue under the lig.patellare

Question 11

Bursa infrapatellaris

Answer 11

Under lig.patellare at tub.tibiae

Question 12

Recessus suprapatellaris

Answer 12

Behind and above patella

Question 13

Recessus subextensorius

Answer 13

Around tendon of m.ext.dig.longus

Question 14

Recessus subpopliteus

Answer 14

Around tendon of m.popliteus

Question 15

Meniscus laterale

Answer 15

Fibrocartilage between femur and tibia

Question 16

Meniscus mediale

Answer 16

Fibrocartilage between femur and tibia

Question 17

Fibrocartilago parapatellaris

Answer 17

Around patella, on both sides

Question 18

Lig.transversum genus

Answer 18

Connects cranial angles of the two meniscus

Question 19

Ligg.meniscotibiales

Answer 19

From the cranial and caudal ends of both meniscus to the tibia´s…

• Lig.craniale menisci laterale: Area intercondylaris cran. lat.
• Lig.craniale menisci mediale: Area intercond. cran.med.
• Lig.caudal menisci laterale: Incisura poplitea
• Lig.caudale menisci mediale: Area intercond. cau.

Question 20

Lig.cruciatum craniale

Answer 20

From laterale femoral condyle´s caudal axial surface to the area intercond. cran. of tibia

Question 21

Lig.cruciatum caudale

Answer 21

From medial femoral condyle´s cranial axial surface to the area intercon. cau. and incisura poplitea of tibia.

Question 22

Lig.meniscofemorale

Answer 22

From medial femoral condyle´s cau. axial surface to the caudal end of lateral meniscus.

Question 23

Lig.popliteum obliquum

Answer 23

Fibrous reinforcment in cau. wall of joint´s capsule

Question 24

M.popliteus

Answer 24

O: Fossa m.politei on condylus lateralis of femur
I: Twist cau. under lig.collaterale laterale then inserts cau. on prox. of tibia, on linea m.politei
A: Flexes stifle, rotates leg medially

Question 25

M.quadriceps femoris

Answer 25

4 muscle bellies
O: Rectus femoris; Corpus of ilium - area m. recti femoris lat. and med., the 3 vastus from prox. of femur, -med; craniomed., -lat; craniolat, -intermed; cranial
I: Patella, by means of patellar lig. on tub.tibiae
A: Strongest extensor of stifle, m.rectus femoris also flex hip
