INTERNAL MAXILLARY. 136 



Lingual^ ascends obliquely from its origin, which is just above 

 the superior thyroid. It courses between the muscles of the tongue, 

 giving off the dorsalis linguse, subHngual and ranine branches. 



Facial? — This arises above the lingual, is tortuous, becomes im- 

 bedded in the submaxillary gland, .and then passes over the lower 

 jaw, and gives off several branches to the face. 



Siih-?nental^ arises from the last, and supplies the chin. 



Masseteric^ also arises from the facial, and is distributed to the 

 masseter muscle. 



Inferior labial, is spent upon the integuments and muscles between 

 the chin and the lip. 



Siqierior and inferior coronary, surround the lips and mouth. The 

 remainder of the facial artery is distributed by a branch upon the 

 side of the nose and the inner angle of the eye, where it anastomoses 

 with the ophthalmic. 



Inferior pharyngeal, ^^ arises near the bifurcation of the carotid 

 or from the external carotid, and is distributed to the pharynx. It 

 often gives off the 2^osterior meningeal, which enters the cranium 

 through the posterior foramen laceruni. 



Occipital,^ arises from the external carotid a little below the 

 facial, forming a loop with the hypoglossal nerve ; is distributed upon 

 the muscles and integuments, anastomosing with the temporal and 

 its fellows. '^ 



Mastoid,^ — This branch is irregular and uncertain in its origin, 

 and supplies the muscles and glands of the neck. 



Posterior auricular, '^^ arises from the external carotid, ascends 

 obliquely backwards, beneath the parotid gland, and passing between 

 the external meatus and mastoid process, is distributed upon the in- 

 teguments. A branch of it, called stylo-niastoid, enters the stylo- 

 mastoid foramen. 



Transversalis faciei^^ arises from the temporal and sometimes 

 from the carotid ; and crossing the masseter muscle parallel with the 

 duct of Steno, is distributed upon the face. 



The anterior posterior and middle temporal are the terminating 

 branches of the temporal artery. The anterior is distributed upon 

 the temple and arch of the skull. The posterior is distributed upon 

 the integuments on the back of the head. The middle perforates the 

 temporal fascia and supplies the temporal muscle. 



INTERNAL MAXILLARY. 



This* commences at the bifurcation of the external carotid, and 

 pursues a very tortuous course, supplying the back portions of the
