ARTERIES 67 



Cervical Branches : 



Ascending or inferior palatine : between stylo-glossus and 

 stylo-pharyngeus to pharynx near border of internal ptery- 

 goid muscle ; after supplying muscles, tonsil, Eustachian 

 tube, divides near levator palati into two branches, one going 

 to supply soft palate, glands, etc. , the other to tonsil ; anas. 

 tonsillar and artery of opposite side. 



Tonsillar : penetrates superior constrictor of pharynx to 

 supply tonsil and root of tongue; anas, ascending palatine. 



Submaxillary (three or four) to supply submaxillary gland. 



Submental : arises as artery turns round base of jaw, and 

 runs forwards over mylo-hyoid, supplying it and digastric, 

 then to symphysis, there dividing into superficial, which turns 

 round chin ; anas, inferior labial and mental, and a deep 

 branch perforates mylo-hyoid, supplying deep muscles ; anas. 

 sublingual. 



Facial Branches : 



Muscular : to masseter, buccinator, etc. 



Inferior labial : runs beneath depressor anguli oris, to supply 

 lower lip ; anas, inferior coronary, submental, mental. 



Inferior coronary : arises near angle of mouth, tortuous course 

 between mucous membrane of lower lip and orbicularis oris ; 

 anastomoses with opposite fellow. 



Superior coronary : arises with or near preceding, having 

 corresponding course in upper lip ; anastomoses with 

 opposite fellow, supplies a branch, artery of septum, to collu- 

 mella of nose. 



Lateral nasal : turns inwards beneath levator labii superioris 

 alaeque nasi to supply ala and dorsum of nose ; anas, opposite 

 fellow, nasal of ophthalmic, and infra-orbital. 



Angular: terminal branch; anastomoses at inner canthus 

 with nasal of ophthalmic. 



Posterior Branches of External Carotid : 



Occipital : arising from the posterior part of artery, about 

 opposite the facial, runs upwards and backwards beneath 

 digastric, stylo-hyoid, sterno-mastoid, splenius, and trachelo- 

 mastoid to interval between transverse process of atlas and 

 mastoid process, then backwards in the occipital groove, and 

 lying on rectus capitis lateralis, superior oblique and com- 

 plexus ; lastly, piercing the trapezius near insertion, it ascends 

 in company with the great occipital nerve to the back of 

 scalp. Hypoglo^al nerve hooks round it at origin, and 

 the artery crosses in the neck the internal carotid artery, 

 pneumogastric and spinal accessory nerves and internal 

 jugular vein.
