the branches of the internal maxillary artery to the maxillary glands, and after- 

 ward to the deep cervical. 



The lymphatics of the nose can be injected from the subdural and subarachnoid 

 spaces. They terminate in the retro-pharyngeal and supra-hyoid glands. The 

 lymphatics of the tongue chiefly accompany the ranine vein first to the lingual 

 glands and from these to the deep cervical. Those from the anterior part of the 

 tongue and floor of the mouth pierce the Mylo-hyoid muscles and so reach the 

 submaxillary glands. From the upper part of the pharynx the lymphatics pass 

 to the retro-pharyngeal glands ; from the lower part, to the deep cervical glands. 

 From the larynx two sets of vessels arise : an upper, piercing the thyro-hyoid

membrane and joining the superior set of deep glands ; and a lower, perforating 

 the crico-thyroid membrane to join the lower set of deep cervical glands. The 

 lymphatics of the thyroid body accompany the superior and inferior thyroid arte- 

 ries, and open partly into the upper and partly into the lower set of deep cervical 

 glands. 



The Lymphatic Glands of the Neck are divided into two sets, superficial and 

 deep. 



The superficial cervical glands may be arranged in three sets : (1) The 

 submaxillary, eight to ten in number, situated beneath the body of the lower 

 jaw in the submaxillary triangle ; (2) suprahyoid, one or two in number, situated
