THE LYMPH GLANDS OF THE HEAD.

frequently found are : Infra-orbital, which lie along the angle between the nose and 

 the cheek, and below the -margin of the orbit. Their afferents are derived from the 

 surrounding parts ; and their efferents pass to the anterior auricular and the 

 submaxillary lymph glands. Buccinator lymph glands have been found on the 

 superficial surface of the anterior part of the buccinator, both anterior and pos- 

 terior to the anterior facial vein. Those posterior to the vein usually lie close 

 to the point where the parotid duct turns, medially, round the anterior border of 

 the masseter. They receive lymph from the eyelids and cheeks, and transmit it

to the anterior auricular glands. Supra-mandibular lymph glands lie superficial to 

 the mandible at the anterior border of the masseter, between the anterior facial vein 

 and the external maxillary artery. They receive lymph from the region of the 

 lower lip, and transmit it to the anterior auricular and superficial cervical glands. 



Lymphoglandulae Paciales Profundse, The deep facial -lymph glands are 

 very variable both in number and size ; they lie in association with the internal 

 maxillary artery on the external pterygoid muscle, or on the adjacent part of 

 the wall of the pharynx. Their afferent vessels are derived from the orbit, 

 the temporal fossa, the infra-temporal fossa, the palate, the nose, and the cerebral 

 meninges. Their efferent vessels open into the upper deep cervical glands. 



Lymphoglandulae Linguales. The lingual lymph glands lie between the genio- 

 ; glossi muscles and, on the lateral surfaces of the hyo-glossi and genio-glossi muscles,
