muscles (Figs. 796, 797). They receive afferents from the integument of the chin, 



from the lower lip, and from the floor of the mouth ; their efferents pass partly to the 



submaxillary nodes and 



partly to a node of the "^; ''^^* 



superior deep cervical 



group situated on the 



internal jugular vein a 



little above the level at 



which it is crossed by 



the omo-hyoid muscle. 

 The facial nodes 



(lymphoglandulae faciales 



profundae) consist of sev- 

 eral small groups (Fig. 



798). One of these is 



composed of two or three 



nodes situated upon the 



outer surface of the 



horizontal ramus of the 



mandible, in front of 



the anterior border of 



the masseter muscle ; 



these may be termed 



the mandibular nodes. 



A second group is to be 



found resting upon the 



surface of the buccinator 



muscle, and its nodes are therefore termed the buccinator nodes. They are three 



or four in number and are situated in the interval between the facial vein and artery, 



or posterior to the vein, almost opposite the angle of the mouth and either beneath 



or slightly below the

third group is formed by 

 the maxillary nodes, 

 which are somewhat 

 scattered, one or two 

 occurring in the groove 

 formed iDy the junction of 

 the nose and cheek, while 

 another rests upon the 

 malar bone near the lower 

 border of the orbit. These 

 maxillary nodes are nor- 

 mally quite small and may 

 readily be overlooked. 



The afferents for the 

 various groups of facial 

 nodes take their origin 

 in the upper lip, in the 

 integument and mucous 

 membrane of the nose 

 and cheek, and probably, 

 also in the eyelids, the 



conjunctiva, and the lachrymal gland. Their efferents pass to the submaxillary nodes. 

 The lingual nodes (lymphoglandulae linguales) are a number of small enlarge- 

 ments situated upon the vessels which drain the lymphatic capillaries of the tongue. 



They do not possess any very definite grouping and are to be found upon both
