What is the lingual artery?
What is the lingual artery?
The lingual artery is a branch of the external carotid artery. It is the principal artery supplying the tongue, sublingual gland, gingiva and oral mucosa of the floor of the mouth. Within the tongue, it is located deep to the hyoglossus muscle. The lingual artery gives off four branches, three of these are given off in the floor of the mouth.
Where does the anterior lingual artery anastomose?
A distal branch runs medially in the anterior lingual mandibular gingiva and anastomoses with the contralateral artery. An additional branch connects with the submental artery under the mylohyoid muscle.40 The lingual artery will anastomose throughout the tongue area, with more anastomoses occurring anteriorly. 41
Where does the lingual artery cross the hyoid bone?
The lingual artery courses medially to the greater horn of the hyoid bone and crosses inferiorly and facially around the hypoglossal nerve. It then transverses deep to the digastric and stylohyoid muscles and courses between the hyoglossus and genioglossus muscles.
Where does the lingual artery join the incisive neurovascular bundle?
Lingual artery. The incisive neurovascular bundle is found to join other vascular structures in the midsymphyseal region. The genioglossus muscle attaches to the genial tubercle in the midline, and the lingual artery courses through the lingual foramen at the genial tubercle.
Where does the lingual artery and hypoglossal nerve travel?
Both the hypoglossal nerve and the lingual neurovascular bundles travel in the inferolateral portions of the tongue base.57 The dorsal lingual arteries are branches of the lingual artery that travel from the lateral portion of the tongue toward the midline near the junction of the oral tongue and the tongue base.
