.
It then curves downward and forward, forming a loop which is crossed by the hypoglossal nerve
, and passing beneath the Digastricus and Stylohyoideus it runs horizontally forward, beneath the Hyoglossus
, and finally, ascending almost perpendicularly to the tongue, turns forward on its lower surface as far as the tip, under the name of the deep lingual artery (profunda linguae ).

Path
It first runs obliquely upward and medialward to the greater cornuGreater cornu
The greater cornua of the hyoid bone project backward from the lateral borders of the body; they are flattened from above downward and diminish in size from before backward; each ends in a tubercle to which is fixed the lateral hyothyroid ligament.The upper surface is rough close to its lateral...
of the hyoid bone
Hyoid bone
The hyoid bone is a horseshoe-shaped bone situated in the anterior midline of the neck between the chin and the thyroid cartilage. At rest, it lies at the level of the base of the mandible in the front and the third cervical vertebra behind.Unlike other bones, the hyoid is only distantly...

Hypoglossal nerve
The hypoglossal nerve is the twelfth cranial nerve , leading to the tongue. The nerve arises from the hypoglossal nucleus and emerges from the medulla oblongata in the preolivary sulcus separating the olive and the pyramid. It then passes through the hypoglossal canal...
, and passing beneath the Digastricus and Stylohyoideus it runs horizontally forward, beneath the Hyoglossus
Hyoglossus
The Hyoglossus, thin and quadrilateral, arises from the side of the body and from the whole length of the greater cornu of the hyoid bone, and passes almost vertically upward to enter the side of the tongue, between the Styloglossus and Longitudinalis inferior....

Branches
- suprahyoid branch of lingual arterySuprahyoid branch of lingual arteryThe suprahyoid branch of lingual artery runs along the upper border of the hyoid bone, supplying the muscles attached to it and anastomosing with its fellow of the opposite side....
- dorsal lingual branches of lingual arteryDorsal lingual branches of lingual arteryThe dorsal lingual branches of lingual artery consist usually of two or three small branches which arise beneath the Hyoglossus.They ascend to the back part of the dorsum of the tongue, and supply the mucous membrane in this situation, the glossopalatine arch, the tonsil, soft palate, and...
- deep lingual arteryDeep lingual arteryThe deep lingual 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 surface of the tongue, below the Longitudinalis inferior, and above the mucous membrane.It lies on the...
- sublingual arterySublingual arteryThe Sublingual Artery arises at the anterior margin of the Hyoglossus, and runs forward between the Genioglossus and Mylohyoideus to the sublingual gland....
