Anatomical terminology]

The lingual artery arises from the

external carotid artery between the superior thyroid artery and facial artery.[1] It can be located easily in the tongue
.

Structure

The lingual artery first branches off from the external carotid artery.

greater horns of the hyoid bone.[1]

It then curves downward and forward, forming a loop which is crossed by the

profunda linguae
).

Branches

The lingual artery gives 4 main branches: the

sublingual artery, the suprahyoid branch, and the dorsal lingual branch.[1]

Deep lingual artery

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

longitudinalis inferior, and above the mucous membrane
.

It lies on the lateral side of the

frenulum linguæ
.

Sublingual artery

The sublingual artery arises at the anterior margin of the hyoglossus, and runs forward between the genioglossus and mylohyoid muscle to the sublingual gland.[3]

It supplies the gland and gives branches to the mylohyoideus and neighboring muscles, and to the mucous membrane of the mouth and gums.

One branch runs behind the

mandible in the substance of the gum to anastomose with a similar artery from the other side; another pierces the mylohyoideus and anastomoses with the submental branch of the facial artery
.

Other branches

  1. The suprahyoid branch of the lingual artery runs along the upper border of the hyoid bone, supplying oxygenated blood to the muscles attached to it and joining (anastomosing) with its fellow of the opposite side.
  2. The dorsal lingual branches of lingual artery consist usually of two or three small branches which arise beneath the
    glossopalatine arch, the tonsil, soft palate, and epiglottis
    ; anastomosing with the vessels of the opposite side.

Function

The lingual artery supplies the tongue.[6] It also supplies the palatine tonsils.[7]
