Vessels of the Equine Pelvic Limb

Question 0

Saphenous a.

Answer 0

Anastamoses from caudal tibial a. and joins with caudal femoral. Cranial branch is superficial and goes to medial tarsus and distal structures. The caudal branch has an S shaped anastamosis from the caudal tibial a. before branching at the tarsus.

Question 1

Femoral a.

Answer 1

Branches into saphenous a. and caudal femoral a.; it is a continuation of the external ilia a. exiting the vascular lacuna

Question 2

Caudal femoral a.

Answer 2

There is not proximal/middle/distal caudal femoral a. ONLY a caudal femoral a. It is near where the the distal caudal femoral a. is in the canine.

Question 3

Popliteal a.

Answer 3

Continuation of the femoral a. after the caudal femoral a. branches off

Question 4

Cranial tibial a.

Answer 4

continuation of the popliteal a. as the cranial and caudal tibial a. branch

Question 5

Dorsal pedal a.

Answer 5

continuation of the cranial tibial a. at the tarsus, joins with a branch from the saphenous a.

Question 6

Dorsal metatarsal a. III

Answer 6

aka great metatarsal a.; major blood supply to the digit anastamoses with branches from saphenous a. at the level of the fetlock; branches into medial/lateral plantar digital a.

Question 7

Sciatic n.

Answer 7

Branches into common peroneal n. and tibial n.

Question 8

Common peroneal n.

Answer 8

Lateral extensor m., cutaneous distribution to lateral leg, damage results in knuckling over

Question 9

Superficial peroneal n.

Answer 9

Cutaneous distribution to lateral aspect of crus to fetlock, lateral digital extensor m.

Question 10

Deep peroneal n.

Answer 10

cutaneous distribution to the pes; branches into medial and lateral dorsal metatarsal n.

Question 11

Medial dorsal metatarsal n.

Answer 11

cutaneous distribution to dorsal metatarsus; goes to medial dorsal digital n. (cutaneous distribution to dorsal digit)

Question 12

Lateral dorsal metatarsal n.

Answer 12

cutaneous distribution to dorsal metatarsus; runs with great metatarsal a.; runs into lateral dorsal digital n. which provides cutaneous distribution to the dorsal digit

Question 13

Tibial n.

Answer 13

Branches into medial and lateral plantar n.

Question 14

Medial plantar n.

Answer 14

cutaneous distribution to medioplantar metatarsal

Question 15

Medial plantar digital n.

Answer 15

Cutaneous distribution to dorsal digit

Question 16

Communicating branch

Answer 16

Between medial and lateral plantar n.

Question 17

Lateral plantar n.

Answer 17

Goes to interosseus m., cutaneous distribution to lateroplantar metatarsus
