Arteria lingualis

Radiopaedia • CC-by-nc-sa 3.0 • de

The lingual artery is one of the branches of the external carotid artery and supplies the oral floor and tongue.

Summary

origin: branch of the external carotid artery at the level of the C3
course: towards hyoid bone, then loops down towards the tongue
supply: oral floor and tongue
termination: tongue
key relationships: loop is crossed by the hypoglossal nerve

Variant anatomy

The facial artery may arise from a common trunk with the lingual artery, the linguofacial trunk.
