THE CAROTID ARTERIES IN THE RABBIT 109 



leave the common carotid artery together as an innominate artery. The 

 superficial temporal is much smaller than the internal maxillary and can 

 be regarded as a branch of the latter. 



Fig. 3. The innominate of the internal carotid and occipital and the 

 superficial temporal are close to each other, while the lingual, external 

 maxillary and inferior alveola may be regarded as branches from the 

 Internal maxillary. 



Fig. 4. The external maxillary and lingual arteries arise as an innomi- 

 nate from the common carotid. The occipital and the internal carotid 

 arteries are in the reverse sequence from the condition shown in Figs. 

 2 and 3, and the former passes mesad to the latter. The inferior alveola 

 is a branch from the external carotid. 



Fig. 5. The occipital leaves the superficial temporal close to the lat- 

 ter's base; the external maxillary and the lingual arteries arise close 

 together from the external carotid while the inferior alveola is at the 

 base of the internal maxillary. 



Fig. 6. The external carotid artery in this case terminates in three 

 branches: the lingual, superficial temporal and internal maxillary, the 

 external maxillary and inferior alveola being branches of the latter. 



Fig. 7. The external carotid artery terminates in three branches: 

 the external maxillary, the internal maxillary and superficial temporal. 

 Note the comparatively long innominate which divides to form the occipi- 

 tal and internal carotid arteries. 



Fig. 8. The lingual and external maxillary arteries originate close to 

 the junction of the internal maxillary and superficial temporal arteries. 



Fig. 10. The occipital artery is a branch of the superficial temporal 

 which leaves the latter well cephalad. 



Fig. 9. The external carotid terminates in two innominate arteries, 

 one giving rise to the lingual and external maxillary arteries, the other 

 forming the internal maxillary and superficial temporal arteries. The 

 occipital branch Is small and comes off of a point of junction of the two 

 Innominates. 



Fig. 11. All the branches of the common carotid are close to one 

 another forming a sort of corona radiata at its termination. 



Fig. 12. The common carotid artery breaks in this case into three 

 Innominate arteries: the external maxillary-lingual, the internal maxil- 

 lary-superficial temporal and the internal carotid-occipital arteries.
