FIG. 74. Dissection to show the relations of the External Carotid Artery 

 and the deep part of the External Maxillary Artery. The parotid gland 

 and the posterior part of the ramus of the mandible and the muscles 

 attached to it have been removed. The terminal branches of the facial 

 nerve have been cut and the terminal parts left in situ. 

 In this specimen the greater part of the posterior facial vein joined the 



external jugular vein. The lingual vein joined the common facial vein ; and 



the origin of the external maxillary artery was deep to the posterior belly of 



the digastric muscle. 



cervical part of the external maxillary artery can be studied
