62 EQUINE ANATOMY. 



lary artery of the tibia; 3 — tarsal articular branches; 

 4 — cutaneous brandies. 



Plantar. — One each side of the perforans tendon, 

 thej run down in the tarsal arch to the suspensory 

 ligament and anastomose with the perforating pedal 

 artery. Collateral branches : 1 — tarsal articular ; 2 — 

 superficial arteries to the tendons ; 3 — deep external 

 and internal interosseous plantar arteries. 



Anterior tibial. — Runs through the tibial arcli on 

 the anterior face of the tibia, under the flexor metatarsi, 

 and at the tibio-tarsal joint becomes the pedal, after 

 sendins: off collateral muscular branches. 



Pedal. — Passes in front of the hock joint, bending 

 outwards, and on a level with the lower row of bones, 

 divides into perforating pedal and metatarso-pedal 

 arteries. 



Perforating pedal. — Runs through the hock joint 

 and anastomoses posteriorly with the plantar artery of 

 the posterior tibial. 



Metatarso-pedal. — Passes in the fissure outside of 

 the large metatarsal bone, forward of the external 

 rudimentary one, then to the posterior face of the first 

 named bone above the sesamoid groove, and terminates 

 in the collaterals of the digit or the digital arteries. 

 Collateral branches are tendinous, ligamentous, cutane- 

 ous and articular.
