294 GENERAL ACCOUNT OF THE INTERNAL ILIAC. 



N. The Inner Condyle. 



o. The Belly of the Gastrocnemius Muscle. 



p. The Soleus Muscle. 



Q. The Achilles Tendon. 



R. The Tibia. 



s. The Flexor Longus Pollicis. 



T. The Flexor Digitorum Communis. 



1. The Internal Iliac Artery ; giving off. 



2. Hypo gastric Artery. 



3. 3. Ischiatic Artery. 

 4.4. The Pudic Artery. 



5. The Obturator Artery. 



6. 6. The Gluteal Artery. 



7. A branch from the Internal Circumflex Artery. 



8. Branches of the Perforating Arteries of the Profunda. 



9. The Popliteal Artery after it has pierced the Triceps Muscle. 



10. Those branches sent off from the main artery as it is passing the ten- 

 don ; they are called the perforating branches of the Popliteal Artery. 



1 1 . The Upper and Internal Articular Artery. 



12. The Upper External Articular Artery. 



13. The Lower External Articular Artery. 



14. The Lower Internal Articular Artery. 



15. The Posterior Tibial Artery ; the Anterior Tibial Artery (see plate, 

 page 308) is a branch sent off from this. 



16. The Peroneal Artery, or Fibular Artery. 



17. The Posterior Tibial Artery appears here again from under the Soleus 

 Muscle. 



18. The Fibular or Peroneal Artery; it is seen to form large inosculations 

 with the Tibial Artery. 



19. A remarkable inosculation betwixt the Tibial and Fibular Arteries. 



20. The External Plantar Artery. 



21. The Internal Plantar Artery. 



The Internal Iliac, or Hypogastric, 



Is distributed, in part, to the viscera of the pelvis and the 

 organs of generation, and also to the large muscles exterior to 

 the pelvis : it is, therefore, very large, although not quite equal 

 to the External Iliac. But in the fetus where it gives off on 

 each side the umbilical artery it is double the size of the exter- 

 nal. 



It has already been mentioned, that in the foetal state, this 

 vessel appears to continue in a curved direction from its origin
