Tributaries. The right lymphatic duct receives the lymph from the right side 

 of the head and neck through the right jugular trunk; from the right upper extremity 

 through the right subclavian trunk; from the right side of the thorax, right lung,

THE LYMPHATICS OF THE HEAD,. FACE, AND NECK. 



The Lymph Glands of the Head (Fig. 602). 



The lymph glands of the head are arranged in the following groups: 



Occipital. Facial. 



Deep Facial. 



Posterior Auricular. 

 Anterior Auricular. 

 Parotid. 



Lingual. 

 Retropharyngeal. 



The occipital glands (lymphoglandulce occipitales) , one to three in nu her, are 

 placed on the back of the head close to the margin of the Trapezius and resting 

 on the insertion of the Semispinalis capitis. Their afferent vessels drain the occipi- 

 tal region of the scalp, while their efferents pass to the superior deep cervical 

 glands.
