liver, In addition, they receive vessels from the superior deep cervical glands. 

 The efferents of the superior deep cervical glands pass partly to the inferior deep 

 cervical glands and partly to a trunk which unites with the efferent vessel of the 

 inferior deep cervical glands and forms the jugular trunk. On the right side, this 

 trunk ends in the junction of the internal jugular and subclavian veins; on the left 

 side it joins the thoracic duct.

FIG. 606. The superficial lymph glands and lymphatic vessels of the upper extremity. 



The lymphatic vessels of the skin and muscles of the neck pass to the deep cervical 

 glands. From the upper part of the pharynx the lymphatic vessels pass to the retro- 

 pharyngeal, from the lower part to the deep cervical glands. From the larynx 

 two sets of vessels arise, an upper and a lower. The vessels of the upper set pierce 

 the hyothyroid membrane and join the superior deep cervical glands. Of the 

 lower set, some pierce the conus elasticus and join the pretracheal and pre- 

 laryngeal glands; others run between the cricoid and first tracheal ring and enter 

 the inferior deep cervical glands. The lymphatic vessels of the thyroid gland con- 

 sist of two sets, an upper, which accompanies the superior thyroid artery and enters 

 the superior deep cervical glands, and a lower, which runs partly to the pretracheal
