DORSALIS PEDIS ARTERY. 329 



Branches. The branches of the Anterior Tibial Artery are the 



Recurrent, 

 Muscular, 

 External malleolar, 

 Internal malleolar. 



The Recurrent branch passes upwards beneath the origin of the tibialii 

 anticus muscle to the front of the knee joint, upon which it is distributed, 

 anastomosing with the articular arteries. 



The Muscular branches are very numerous, they supply the muscles of 

 the anterior tibial region. 



The Malleolar arteries are distributed to the ankle joint ; the external 

 passing beneath the tendons of the extensor longus digitorum and pero- 

 neus tertius, inosculates with the anterior peroneal artery and with the 

 branches of the dorsalis pedis ; the internal, beneath the tendons of the 

 extensor proprius pollicis and tibialis anticus, inosculates with branches 

 of the posterior tibial and internal plantar artery. They supply branches 

 to the ankle joint. 



The DORSALIS PEDIS ARTERY is continued forward along the tibial side 

 of the dorsum of the foot, from the ankle to the base of the metatarsal bone 

 of the great toe, where it divides into two branches, the dorsalis hallucis 

 and communicating. 



Relations. The dorsalis pedis is situated along the outer border of the 

 tendon of the extensor proprius pollicis ; on its fibular side is the inner- 

 most tendon of the extensor longus digitorum, and near its termination it. 

 is crossed by the inner tendon of the extensor brevis digitorum. It is ac 

 companied by venae comites, and has the continuation of the anterior tibial 

 nerve to its outer side.

the soleus. 8. The annular ligament beneath which the extensor tendons and the an 

 terior tibial artery pass into the dorsum of the foot. 9. The anterior tibial artery. 10 

 Its recurrent branch inosculating with (2) the inferior articular, and (1) the superior 

 articular arteries, branches of the popliteal. 11. The internal malleolar artery. 17. 

 The external malleolar inosculating with the anterior peroneal artery 12. 13. The doi- 

 salis pedis artery. 14. The tarsea and metatarsea arteries; the tarsea is nearest th* 

 ankle, the metatarsea is seen giving off the interossese. 15. The dorsalis hallucis artery. 

 10. The communicating branch.
