* The anterior aspect of the leg and foot, showing the anterior tibial and dorsalis 

 pedis arteries, with their branches. 1 . The tendon of insertion of the quadriceps ex- 

 tensor muscle. 2. The insertion of the ligamentum patellae into the lower border of 

 the patella. 3. The tibia. 4. The extensor proprius pollicis muscle. 5. The extensor 

 longus digitorum. 6. The peronei muscles. 7. The inner belly of the gastrocncmius 

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

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

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

 dorsalis pedis artery. 14. The tarsea and metatarsea arteries ; the tarsea is nearest 

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

 artery. 1 6. The communicating branch. 



t A posterior view of the leg, showing the popliteal and posterior tibial artery. 1. 

 The tendons forming the inner hamstring. 2. The tendon of the biceps forming the 

 outer hamstring. 3. The popliteus muscle. 4. The flexor longus digitorum. 5. The 

 tibialis posticus. 6. The fibula ; immediately below the figure is the origin of the 

 flexor longus pollicis ; the muscle has been removed in order to expose the peroneal 

 artery. 7. The peronei muscles, longus and brevis. 8. The lower part of the flexor 

 longus pollicis muscle with its tendon. 9. The popliteal artery giving off its articular 

 and muscular branches ; the two superior articular are seen in the upper part of the 

 popliteal space passing above the two heads of the gastrocnemius muscle, which are 

 cut through near to their origin. The two inferior are in relation with the popliteus 

 muscle. 10. The anterior tibial artery passing through the angular interspace between 

 the two heads of the tibialis posticus muscle. 11. The posterior tibial artery. 12. The 

 relative position of the tendons and artery at the inner ankle from within outwards, 

 previously to their passing beneath the internal annular ligament. 13. The peroneal 

 artery, dividing into two branches ; the anterior peroneal is seen piercing the inter- 

 osseous membrane. 14. The posterior peroneal.
