What muscles does the lingual artery supply?
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.
What is the hyoglossus muscle?
The hyoglossus muscle is one of the four intrinsic muscles of the tongue. It is a quadrilateral muscle that originates along the whole length of the hyoid bone and inserts into the side of the tongue. The hyoglossus acts to both depress and retract the tongue.
Which of the arteries supply the genioglossus and the hyoglossus muscle?
The sublingual artery
[1] The sublingual artery is the third branch and supplies the sublingual gland, the genioglossus, the geniohyoid, the mylohyoid, the buccal and gingival mucosa, and the mandible.
What is the origin of the hyoglossus muscle?
hyoid bone The hyoglossus muscles originate on each side from the whole length of the greater cornua and also from the body of the hyoid. They are inserted into the posterior half or more of the sides of the tongue.
What nerve runs with the lingual artery?
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.
