364 ABSORBENTS OF THE HEAD AND NECK. 



CHAPTER XI. 



OF THE ABSORBENTS OF THE HEAD AND NECK ; OF THE UPPER 

 EXTREMITIES, AND THE JJPPER PART OF THE TRUNK OF 

 THE BODY. 



THE absorbents from the various parts of the bead pass 

 through glands, which are situated on the neck or the lower 

 part of the head. Those on the head are the least numerous, 

 and also the least in size. Some of them, which are generally 

 small, lie about the parotid gland. Several of them, which are 

 also small, are on the occiput, below and behind the mastoid 

 process. Sometimes there are two or three on the cheek, near 

 the basis of the lower jaw, about the anterior edge of the rnas- 

 seter muscle. Below the lower jaw, in contact with the sub- 

 maxillary gland and anterior to it, there are always a number 

 of these glands, which are generally small, but often swelled 

 during infancy. 



The Glands on the Neck are the most numerous. Many of 

 them are within the sterno-mastoid muscle, and accompany 

 the internal jugular vein and the carotid artery down to the 

 first rib. Many also lie in the triangular space between the 

 sterno-mastoid muscle, the trapezius, and the clavicle ; therefore 

 it has been truly said that the glands of the neck are more 

 numerous than those of any other part except the mesentery. 

 They are frequently called Glandule Concatenate. It has 

 already been mentioned that the various absorbents, which are 

 connected with these glands, unite on each side into a trunk, 

 which on the left passes into the thoracic duct, and on the right 

 into the common trunk of the absorbents of that side. 



Of the Absorbents of the Head and Neck. 



There is the greatest reason to believe that the brain and its 

 appendages are supplied with absorbents like the other parts.
