THE LYMPHATICS 



Some of the facial lymphatics pass through these on their way to the submaxillary 

 glands. 



(5) The submaxillary lymphatic glands are situated in the digastrir triangle, 

 beneath the body of the lower jaw. They vary from eight to twelve in number. 

 They receive some of the lymphatics from the face, i.e. from the upper and lower 

 lips and side of the nose; the lymphatics from the iioor of the mouth, from the 

 front part of the tongue, and from the sublingual and submaxillary salivary glands, 

 and the anterior efferent vessels from the parotid lymphatic glands. Their efferent 

 vessels terminate partly in the deep, and partly in the superficial cervical lymphatic 

 glands. Two or three glands situated in the middle line between the anterior bellies

of the digastric muscles are sometimes distinguished as the suprahyoid lym-

2. The vertical set of superficial glands of the neck — four to six in number, 

 known as the superficial cervical chain — are situated chiefly in the posterior 

 triangle of the neck, along the course of the external jugular vein, lietween the 

 platysma and the deep fascia. Small superficial glands are also found in the front 

 of the neck between the hyoid Ixrne and the sternum, and posteriorly over the 

 trapezius muscle. The superficial cervical glands receive the vessels from the 

 occipital glands, and from the posterior auricular glands, and part of tliose from 

 the parotid and submaxillary glands. They also receive the lymj)hatics from the
