Question 1

Metatarsal bones 2-4

Answer 1

Mt2- Medial splint bone
Mt3- Cannon Bone (large and in the middle)
Mt4- Lateral splint bone

Question 2

Tarsal bones

Answer 2

• calcaneus (largest bone of hock; lateral)
• talus (medial bone of proximal row and forms trochlea that articulates with distal end of tibia)
• Central tarsal bone (articulates proximally with alus and vitally with fused 1st 2nd and 3rd tarsal bones)
• 1st and 2nd tarsal bones; fused
• 3rd tarsal bone (between fused 1 and 2 and T4)
• 4th tarsal bone lateral distal bone

Question 3

tarsal canal

Answer 3

formed by T4, T3, T1+2

Question 4

T1 + 2 gives attachments to

Answer 4

medial collateral ligament and to medial branch of tibias cranial tendon

Question 5

T4 provides attachments

Answer 5

for lateral collateral and long plantar ligaments

Question 6

calcanean bursa

Answer 6

• bounded superficially by superficial flexor tendon

- bounded deeply by insertion of gastrocnemius and calcanean tuber (

Question 7

calcanean bursa

Answer 7

• bounded superficially by superficial flexor tendon

- bounded deeply by insertion of gastrocnemius and calcanean tuber

Question 8

medial plantar nerve

Answer 8

inclines from plantar surface of deep flexor tendon to groove between flexor tendons and suspensory and descends to fetlock

Question 9

lateral plantar nerve

Answer 9

passes laterally between superficial and deep flexor tendons, reaches groove between the flexors and the suspensory on the lateral side, gives off deep branch and descends to fetlock

Question 10

deep branch of the lateral plantar nerve

Answer 10

penetrates proximal end of suspensory and supplies it and bifurcates to form medial and lateral plantar metatarsal nerves

Question 11

medial and lateral plantar metatarsal nerves

Answer 11

come from bifurcation of deep branch of lateral plantar nerve; descend on axial surface of the splint bones, emerge at splint bones distal

Question 12

lateral and medial dorsal metatarsal nerves

Answer 12

innervate hock joint; come from deep branch of common fibular nerve, a branch of the sciatic nerve

Question 13

communicating branch innervation hindlimb

Answer 13

between medial plantar and lateral plantar nerve at level of mid-cannon bone, caudally on surface of SDF tendon. Has implications for anesthesia when doing regional blocks

Question 14

cranial tibial muscle and joint accessability

Answer 14

cr tibial muscle branches and the medial branch is the cunean tendon which runs over the DIT joint; can push this proximally +/- caudally for better access to joint

Question 15

cranial tibial insertion to tarsal bones

Answer 15

fused 1/2 tarsal bones

Question 16

fibularis (peroneus) tertius insertions tarsal bones

Answer 16

Dorsal branch to Mt3
Medial branch to T3?
Deep Lateral Branch T4
Superficial Lateral branch calcaneus

Question 17

peroneus tertius and cranial tibial relationship

Answer 17

peroneus tertius forms a ring like tunnel at the level of the talus and the cranial tibial runs through it then gives off medial branch which is cunean tendon which runs over distal intertarsal joint which can interfere when trying to inject the joint may need to move it proximally +/- caudally
