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. (See enlarged image)
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 retropharyngeal, 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 prelaryngeal glands; others run between the cricoid and first tracheal ring and enter the inferior deep cervical glands. The lymphatic vessels of the thyroid gland consist 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
