The pharyngeal veins commence in the pharyngeal plexus superficial to the pharynx. The pharyngeal veins receive as tributaries meningeal vein, and the vein of the pterygoid canal. The pharyngeal veins typically empty into the internal jugular vein (but may occasionally instead empty into the facial vein, lingual vein, or superior thyroid vein). [1]
The pharyngeal plexus (venous) is a network of veins beginning in the pharyngeal (nerve) plexus on the outer surface of the pharynx, and, after receiving some posterior meningeal veins and the vein of the pterygoid canal, end in the internal jugular.

The lingual veins drain into the internal jugular vein. The floor of the mouth also receives its blood supply from the lingual artery. [ 6 ] There is also a secondary blood supply to the root of tongue from the tonsillar branch of the facial artery and the ascending pharyngeal artery .
