which is of considerable size in other animals. Placed within the 

 il nietatai>al bone, it anastomoses, by its inferior extremity, with a 

 branch of the nietatnrsal pedal artery. The intt mnl indronseatts plantar artery 

 may be considered, if wo would neglect the study of analogies, as the continua- 

 tion of the perforating pedal artery, which it rivals in volume. It descends 

 to tho external side of the internal metatarsal bone, beneath the margin of the 

 MII ciis >ry ligament of the fetlock, and terminates a little above the tubercle 

 of the external metatarsal bone, in uniting at a very acute angle with the 

 inetat:irso-pedal artery. It gives off on its tract : the medullary branch of 

 the principal mctatarsal bone ; a small branch to the external interosseous 

 artery ; several ramuscules which transversely cross the posterior border 

 of the internal metatarsal bone to supply the cellular tissue, the skin, and 

 the tendons applied to the median metatarsal bone. 



2. Anterior Tibial Artery. (Fig. 278, 1.) 

 'ration. EXJXISC the artery by removing the anterior muscles of the leg. 



The anterior tibial artery is the largest of the two branches terminating 

 the popliteal trunk. It traverses the tibial or tibio-peroneal arch, and, with 

 itullite veins, places itself on the anterior aspect of the tibia, down 

 which it passes by following the deep face of the flexor muscle of the 

 metatarsus. On reaching the front of the tibio-tarsal articulation, it loses 

 its name and takes that of the pedal artery. 



The anterior tibial artery gives off a great number of collateral branches, 

 which are principally distributed among the tibial muscles. One of them, 

 uding along the fibula, beneath the lateral extensor muscle of tho 

 phalanges, clearly represents a trace of the peroneal artery of Man. 



3. Pedal Artery. (Fig. 278, 1'.) 



A continuation of the anterior tibial artery, whose name changes on its 

 arrival in the region of the foot, the pedal artery courses downward over tho 

 anterior face of the tibio-tarsal articulation, by bending slightly outwards, 

 and passing beneath the cuboid branch of the flexor muscle of the metatarsus. 

 At the second row of tarsal bones it divides into two branches, which wo 

 will designate the perforating pedal, and the metatarso-pedal arteries, 1 the 

 latter continued inferiorly by the digital arteries, or collaterals of the digit. 



The collateral branches emanating from this vessel are all articular 

 cutaneous, and of no importance. 2 



PERFORATING PEDAL ARTERY. It crosses the tarsus from before to 



behind, by passing, with a venous branch, into tho canal between the 



cultoid, scaphoid, and groat cuneiform bones; it then joins the arch formed 



by the anastomoses of the two plantar arteries terminal divisions of the 



.-ior tibial (Fig. 278, 2).
