Origin

The sublingual artery arises from the lingual artery, a branch of the external carotid artery.

Course

The sublingual artery arises from the lingual artery at the anterior border of the hyoglossus muscle. It courses anteriorly between the genioglossus and mylohyoid muscles towards the sublingual gland.

Branches

There are no named branches of the sublingual artery; however, it does contribute to several anastomoses. One branch pierces the mylohyoid muscle to join the submental branches of the facial artery. Another unnamed branch passes through the gingiva of the mandible to form an anastomosis with its fellow branch from the opposite side. From this anastomosis, a single artery arises and passes through the lingual foramen of the mandible.

Supplied Structures

The sublingual artery supplies the sublingual gland, the mylohyoid muscle, and the buccal and gingival mucous membranes.

Artery

When the artery is occluded blood is forced through the collateral vessels, drastically increasing fluid shear stress and triggering an inflammatory response which drives vessel remodeling.
