Lymphoglandulae Cervicales Profundse Superiores et Inferiores. The deep 

 cervical lymph glands lie in the anterior and posterior triangles of the' neck and 

 under cover of the sterno-mastoid muscle. They form a more or less continuous 

 sheet of gland nodules and inter-communicating lymph vessels ; but the glands are 

 divided into two main groupsj the (a) superior, and (&) inferior, and each group is 

 separable into (1) medial, and (2) lateral components. 



(a) The Superior Deep Cervical Lymph Glands. (1) The medial group of upper 

 deep cervical lymph glands lies on the superficial surface of the internal jugular 

 vein and in the carotid triangle of the neck. One of the largest, which is closely 

 associated with the tongue, lips, gums, cheeks, and the outer part of the nose, is

 which the figure was made. Compare Fig. 799. 



frequently situated in the region of the union of the common facial vein with the 

 internal jugular vein. The lowest gland of the group lies on the lateral surface of 

 the internal jugular vein immediately above the omo-hyoid muscle ; it receives a 

 communication from the submental glands. The highest members of the group 

 may be under cover of the postero-medial surface of the parotid gland, in associa- 

 tion with the posterior belly of the digastric muscle. (2) The members of the 

 lateral group of superior deep cervical lymph glands lie under cover of the posterior 

 part of the upper portion of the sterno-mastoid, and in the upper part of the 

 posterior triangle of the neck. They are embedded in the fat-laden fascia which 

 covers the roots of the cervical plexus and the upper part of the brachial plexus,
