integuments of the neck and from tlie external ear. Their efferent vessels open 

 into the deep chain of cervical glands. 



II. THE DEEP LYMPHATIC VESSELS AND GLANDS 

 OF THE HEAD AND NECK 



A. The Deep Lymphatic Vessels of the Head and Neck 



The deep lymphatic vessels of the head and neck may he divided into 

 the lymphatics of the cranium, the orbit, the temporal and zygomatic fossa?, the 

 nose, the mouth and tongue, the pharynx, the larynx, the up])er part of the 

 oesophagus and trachea, and the thyroid body. They roughly follow the course of 

 the deep arteries, and terminate in the deep cervical chain of lymphatic glands 

 which accompany the common carotid artery and internal jugular vein. 



1. The lymphatics from the interior of the cranium are divided into the

Efferent vessels to deep cervical 



meningeal and the cerebral. The meningeal accompany the meningeal arteries 

 through the various foramina in the I)as(! of the skull, and terminate in the deep 

 cervical chain. The cerebral lymphatics pass in like manner with the cerebral 

 vessels (the internal carotid and verteln-al arteries, and the internal jugular vein), 

 through the corresponding foramina in the base of the skull, and join the deep 

 lymphatic chain. The origin of the cerebral lym])hatics and the lymphatics from 

 the clioroid plexus are described in the Anatomy of the Brain (page 678). 



2. The lymphatics of the orbit j)ass witli tlic infraorbital vein into the s])heno- 

 maxillary fossa, and thence with the internal maxillary vein into the internal 

 maxillary and deep parotid glands. (For description of the lymphatics of the eye- 

 ball, see page 852. ) 



3. The lymphatics from the temporal and zygomatic fossae run with 

 the arteries in these situations, and, after passing througli the internal maxillary 

 glands, join the deep cervical chain. 



4. The lymphatics from the interior of the nose accompany the arteries 

 supplying that cavity, and terminate, in jiart in the lyiii])liatics of the pharynx, but 

 chiefly in the deep cervical chain. They communicate, through tlie lymphatic
