absent in cows

Question 5

Tarsal Bones

Horse

Answer 5

• distal tarsal bones 1 and 2 fused, rest solely on MT II

- metatarsals II, III, and IV

Question 6

Tarsal Bones

Ox

Answer 6

• central and tarsal bone 4 are fused
• tarsal bones 2 and 3 are fused
• metatarsals III and IV, fused

Question 7

Accessory Ligament of Femoral Head

Answer 7

• only in horse
• extension of prepubic tendon, through acetabular notch, to the femur head
• prevents hip luxation and side kicking

Question 8

Retention Loop

Answer 8

• medial and intermediate patellar ligament

- around trochlear tubercle

Question 9

Long Plantar Ligament

Answer 9

follows plantar aspect of calcaneus, continues onto proximal part of metatarsus

Question 10

Stifle Joint Communication

Answer 10

• tibiotarsal and proximal intertarsal: always
• proximal intertarsal and distal intertarsal: never
• distal intertarsal and tarsometatarsal: sometimes

Question 11

Cunean Tendon

Answer 11

smaller medial branch of cranial tibial tendon

- diverges to cross the medial collateral ligament and inserts on the first and second tarsal bones

Question 12

Intramuscular Injection Site on Horse

Answer 12

semimembranosus muscle

Question 13

Patellar Locking Mechanism

Answer 13

• if patella is engaged over medial trochlear ridge, stifle cannot flex
• patella, parapatellar fibrocartilage, medial, intermediate and lateral patellar ligaments

Question 14

Reciprocal Apparatus

Answer 14

• stifle and hock flex and extend together

- fibularis tertius, fibrous component of SDF, and gastrocnemius

Question 15

Suspensory Apparatus

Answer 15

• interosseus
