66 EQUINE ANATOMY, 



by several ramifications. 4 — The external saphena 

 passes over the external body of the bifemoro-calca- 

 neoiis, downwards to the origin of the tendo-Achillis, 

 on the outside of which it passes over to the tarsus 

 and terminates in the metatarsus. 5 — Branches to 

 the posterior tibial muscles, several in number, coming 

 from the sciatic as it passes between the gemelli of 

 the leg, and then ramifying in these muscles. 6 — Cuta- 

 neous branch as it runs along the tendo-Achillis. 



Jt^LANTAR. — Situated in the tarsal sheath, behind the 

 perforans tendon, they reach the upper extremity of 

 the metatarsus, and separating from each other run on 

 each side of the tendons of the deep fl.exors to the 

 fetlock joint, and terminate as those of the anterior 

 extremity.
