The deep lingual artery (or ranine artery) is the terminal portion of the lingual artery after the sublingual artery is given off.As seen in the picture, it travels superiorly in a tortuous course along the under (ventral) surface of the tongue, below the longitudinalis inferior, and above the mucous membrane.
Blood supply is provided by tonsillar branches of five arteries: the dorsal lingual artery (of the lingual artery), ascending palatine artery (of the facial artery), tonsillar branch (of the facial artery), ascending pharyngeal artery (of the external carotid artery), and the lesser palatine artery (a branch of the descending palatine artery ...
The lingual vein passes medial to the hyoglossus. The lingual artery passes deep to the hyoglossus. Laterally, in between the hyoglossus muscle and the mylohyoid muscle, lay several important structures (from upper to lower): sublingual gland, submandibular duct, lingual nerve, vena comitans of hypoglossal nerve, and the hypoglossal nerve.
The tongue receives its blood supply primarily from the lingual artery, a branch of the external carotid artery. 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 ...
Lingual tonsils are covered externally by stratified squamous epithelium (nonkeratinized) that invaginates inward forming tonsillar crypts. Beneath the epithelium is a layer of lymphoid nodules containing lymphocytes. Mucous glands located at the root of the tongue are drained through several ducts into the crypts of the lingual tonsils.
The inferior alveolar artery (inferior dental artery) is an artery of the head. It is a branch of (the first part of) the maxillary artery.It descends through the infratemporal fossa [1] as part of a neurovascular bundle with the inferior alveolar nerve and vein to the mandibular foramen where it enters and passes anteriorly inside the mandible, supplying the body of mandible and the dental ...
The paired submandibular glands (historically known as submaxillary glands) are major salivary glands located beneath the floor of the mouth.In adult humans, they each weigh about 15 grams and contribute some 60–67% of unstimulated saliva secretion; on stimulation their contribution decreases in proportion as parotid gland secretion rises to 50%.

The vascular supply to the laryngopharynx includes the superior thyroid artery, the lingual artery and the ascending pharyngeal artery. The primary neural supply is from both the vagus and glossopharyngeal nerves.
