What is the lingual artery?

The lingual artery supplies blood to the tongue and oral cavity. This portion of the external carotid artery branches out to supply blood to surrounding tissues. Here’s an overview of the lingual artery’s anatomy, including its structure, location, and anatomical variations. Collagen fibers make up the outer layer of arteries.

How does the lingual artery cross the hypoglossal nerve?

The lingual artery first branches off from the external carotid artery. It runs obliquely upward and medialward to the greater horns of the hyoid bone. It then curves downward and forward, forming a loop which is crossed by the hypoglossal nerve.

What happens if you injure the lingual artery?

Injuring the lingual artery can result in fatal blood loss or tongue necrosis. If the artery becomes inflamed by an injury, it may cause pain and swelling. Chemotherapy may impact the lingual artery and tongue, according to one case study. 1 Pseudoaneurysms of this artery can also happen.

What are the branches of the sublingual artery?

These branches are normally two to three small vessels that branch off the lingual artery medial to the hyoglossus muscle and pass into the posterior aspect of the tongue. The sublingual branch supplies the sublingual gland, mylohyoid muscle and the buccal and gingival mucous membranes.

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.

What is the suprahyoid branch of the lingual artery?

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. The dorsal lingual branches of lingual artery consist usually of two or three small branches which arise beneath the hyoglossus.
