Submandibular lymph nodes

The mandibular lymph nodes ( lymph nodes [ lymph ]. Submandibular ) are a group of three to six lymph nodes at the lower margin of the mandibular body laterally and superficially to the submandibular gland. The catchment area ( tributary area ) of the lymph nodes are cheek, nose, the nasal corner of the eye, lips, palate, jaw and part of the tongue. The lymphatic drainage is via the deep cervical lymph nodes.

In animal anatomy, the lymph nodes are referred to as mandibular lymph [ Lnn. ] And comparative- anatomical assigned to the mandibular Lymphocentrum. It comes in cattle usually only one lymph node on both sides before, in pigs and predators two or more horses and a large package of many small lymph nodes. The lymph node packets from both sides merge in horses forward so that a V-shaped structure is formed. The tributary area largely corresponds to the conditions in humans. The lymphatic drainage is usually done via the Lymphocentrum retropharyngeum, in horses directly into the cranial deep cervical lymph nodes.

In cats and pigs additional mandibular lymph nodes ( lymph mandibular accessorii ) occur, either directly behind the mandibular lymph nodes ( cats) or further away from the confluence of the external jugular vein ( pigs) are.
