ANGIOLOGY 



parotid glands drain the nasal part of the pharynx and the posterior parts of tl 

 nasal cavities; their efferents pass to the superior deep cervical glands. 



The facial glands comprise three groups: (a) infraorbital or maxillary, scattered 

 over the infraorbital region from the groove between the nose and cheek to the 

 zygomatic arch ; (b) buccinator, one or more placed on the Buccinator opposite the 

 angle of the mouth; (c) supramandibular, on the outer surface of the mandible, 

 in front of the Masseter and in contact with the external maxillary artery and 

 anterior facial vein. Their efferent vessels drain the eyelids, the conjunctiva, 

 and the skin and mucous membrane of the nose and cheek; their efferents pass to 

 the submaxillary glands. 



The deep facial glands (lymphoglandulce faciales profunda; internal maxillary 

 glands') are placed beneath the ramus of the mandible, on the outer surface of the 

 Pterygoideus externus, in relation to the internal maxillary artery. Their afferent 

 vessels drain the temporal and infratemporal f ossse and the nasal part of the pharynx 

 their efferents pass to the superior deep cervical glands. 



The lingual glands (lymphoglandulce linguales) are two or three small nodules 

 lying on the Hyoglossus and under the Genioglossus. They form merely glandular 

 substations in the course of the lymphatic vessels of the tongue.

The retropharyngeal glands (Fig. 603), from one to three in number, lie in the 

 buccopharyngeal fascia, behind the upper part of the pharynx and in front of the 

 arch of the atlas, being separated, however, from the latter by the Longus capitis. 

 Their afferents drain the nasal cavities, the nasal part of the pharynx, and the 

 auditory tubes; their efferents pass to the superior deep cervical glands. 



The lymphatic vessels of the scalp are divisible into (a) those of the frontal region, 

 which terminate in the anterior auricular and parotid glands; (6) those of the 

 temporoparietal region, which end in the parotid and posterior auricular glands; 

 and (c) those of the occipital region, which terminate partly in the occipital 

 glands and partly in a trunk which runs down along the posterior border of the 

 Sternocleidomastoideus to end in the inferior deep cervical glands. 



The lymphatic vessels of the auricula and external acoustic meatus are also divisible 

 into three groups: (a) an anterior, from the lateral surface of the auricula arid 

 anterior wall of the meatus to the anterior auricular glands; (6) a posterior, from 

 the margin of the auricula, the upper part of its cranial surface, the internal surface
