THE LYMPH NODES OF THE HEAD AND FACE 779 The submental or suprahyoid nodes (Figs. 556 and 559) are usually two nodes situated between the anterior bellies of the two Digastric muscles and upon the IMylohyoid muscle. They receive lymph from the cutaneous surface of the , from the cutaneous and mucous surfaces of the central portion of the lower lip, from the central portion of the gums, from the floor of the mouth, and from the tip of the tongue. They send some vessels to the submaxillary lymph nodes, and frequently a node is interposed on the anterior belly of the Digastric muscle. They send other vessels to the upper deep cervical nodes. The anterior cervical nodes form an irregular and inconstant group on the front of the larynx and trachea. They may be divided into (a) a superficial set, placed on the anterior jugular vein; (6) a deeper set, which is further sub- divided into prelaryngeal, on the cricothyroid membrane, and pretracheal, on the front of the trachea. The superficial set receives lymph from the posterior auricular and occipital nodes; their efferents empty into the upper deep cervical nodes. The deeper set drains the lower part of the larynx, the thyroid body, and the upper part of the trachea; their efferents pass to the lower nodes of the upper deep cervical group. The retropharyngeal nodes have been described on page 776. MASTOID NODES , STERNOMA5TOID -i^NODE (extcmul If group). I. JUGULAR Fig. 560.—Deep cervical (Po The deep cervical nodes (lymphoglandulae cervicales profimdae) (Figs. 556 and 560) are nimaerous and of large size; they form a chain along the carotid sheath lying by the side of the pharynx, oesophagus, and trachea, and extending from the base of the skull to the root of the neck. They are usually described in two groups: (1) an upper or substemomastoid group {lymphoglandulae cervi- cales profimdae superiores) lying under the Sternomastoid in close relation with the spinal
