Excerpt from Transactions of the New York Academy of Medicine, 1892, Vol. 8 The internal jugular plexus extends also along the large blood vessels to the base of the skull, where it gathers the intracranial ducts. Its deep cervical glands, from ten to twenty in number, are distinguished as upper and lower, the latter being adjacent to and connected with the superficial cervical glands. The upper deep cervical glands collect the ducts of both pharynx and tongue, along which there are three or four lingual glands; also of the inner muscles of the neck, of larynx and thyroid gland. The lingual glands receive most of the lymph from the tongue, the lower part of the pharynx, the deep muscles of the throat and neck, of the larynx and thyroid.
