ARTERIES. 



ing the muscles attached to it, and anastomosing with its fellow of the opposite 

 side. 



The dorsalis linguse (Fig. 279) arises from the lingual artery beneath the Hyo- 

 glossus muscle (which, in the figure, has been partly cut away, to show the 

 vessel) ; ascending to the dorsum of the tongue, it supplies the mucous mem- 

 brane, the tonsil, soft palate, and epiglottis ; anastomosing with its fellow from 

 the opposite side. 



The siiblmgual, which may be described as a branch of bifurcation of the 

 lingual artery, arises at the anterior margin of the Hyo-glossus muscle, and, 

 running forwards and outwards beneath the Mylo-hyoid to the sublingual 

 gland, supplies its substance, giving branches to the Mylo-hyoid and neighbor- 

 ing muscles, the mucous membrane of the mouth and gums.

The ranine may be regarded as the other branch of bifurcation, or, as is more 

 usual, as the continuation of the lingual artery ; it runs along the under surface 

 of the tongue, resting on the Lingualis, and covered by the mucous mem- 

 brane of the mouth ; it lies on the outer side of the Grenio-hyo-glossus, and is 

 covered by the Hyo-glossus and Stylo-glossus, accompanied by the gustatory 

 nerve. On arriving at the tip of the tongue, it anastomoses with the artery 

 of the opposite side. These vessels in the mouth are placed one on each side 

 of the fraenum. 



Surgical Anatomy. The lingual artery may be divided near its origin in cases of cut throat,

 the course of the coronary arteries.
