374 ARTERIES. 



the artery of the opposite side, 

 each side of the frgenum. 



These vessels in the mouth are placed one on 



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

 a complication that not unfrequently happens in this class of wounds, or severe hemorrhage, 

 which cannot be restrained by ordinary means, may ensue from a wound, or deep ulcer of the 

 tongue. In the former case, the primary wound may be enlarged, if necessary, and the bleeding 

 vessel at once secured. In the latter case, it has been suggested that the lingual artery should 

 be tied near its origin. If the student, however, will observe the depth at which this vessel is 

 placed from the surface, the number of important parts which surround it on every side, and 

 its occasional irregularity of origin, the great difficulty of such an operation will be apparent ; 

 under such circumstances, it is more advisable that the external or common carotid should be 

 tied. 



Troublesome hemorrhage may occur in the division of the franum in children, if the ranine 

 artery, which lies on each side of it, is cut through. The' student should remember that the 

 operation is always to be performed with a pair of blunt-pointed scissors, which should be so 

 'held as to divide the part in the direction downwards and backwards ; the ranine artery and 

 veins are then avoided. 



Fig. 209. The Arteries of the Face and Scalp. 



The FACIAL ARTERY (fig. 209) arises a little above the lingual, and ascends 

 obliquely forwards and upwards, beneath the body of the lower jaw, to the sub- 

 maxillary gland, in which it is imbedded ; this maybe called the cervical part of the 

 artery. It then curves upwards over the body of the jaw at the anterior inferior 

 angle of the Masseter muscle, ascends forwards and upwards across the cheek to 

 the angle of the mouth, passes up along the side of the nose, and terminates at 

 the inner canthus of the eye, under the name of the angular artery. This vessel,
