66 THE POCKET ANATOMY 



Anterior Branches of External Carotid. 



Superior thyroid : given off just below great cornu of hyoid, 

 curves downwards and forwards to thyroid body ; anas, fellow 

 of opposite side, inferior thyroid. 



Branches : 



Muscular: to muscles covering it. Sterna -mastoid branch 

 passes downwards and outwards across sheath of common 

 carotid, supplying sterno-mastoid and integument. 



Infra hyoid : runs transversely inwards, along inferior 

 border of hyoid ; anas, with opposite fellow. 



Superior laryngeal : accompanies superior laryngeal nerve, 

 pierceo thyro-hyoid membrane, supplies muscles, glands, and 

 mucous membrane of larynx ; anas, opposite fellow. 



Crico-thyroid : crosses crico-thyroid membrane transversely , 

 anas, opposite fellow. 



Thyroid : to upper and anterior part of gland. 



Lingual : arises from anterior part of artery between superior 

 thyroid and facial arteries, curves upwards and forwards on 

 middle constrictor to tip of great cornu of hyoid, where it is 

 crossed by hypoglossal nerve, thence forwards under hyo- 

 glossus muscle, digastric and stylo-hyoid, parallel with hypo- 

 glossal nerve, finally on genio-hyo-glossus upwards and for- 

 wards to tip of tongue as ranine. 



Branches : 



Supra-hyoid : along superior border of hyoid, supplying 

 muscles, etc. ; anas, opposite fellow. 



Dorsalis lingua: ascends to dorsum of tongue; anas, oppo- 

 site fellow, supplies mucous membrane, tonsil, epiglottis, 

 soft palate, etc. 



Sublingtial : runs forwards and outwards to supply sub- 

 lingual gland, adjacent muscles and mucous membrane. 



Ranine : continuation of the lingual to tip of tongue, accom- 

 panies gustatory nerve ; anas, opposite fellow. 



Facial : arises near angle of inferior maxilla, directed for- 

 wards and upwards beneath digastric and stylo-hyoid muscles 

 in groove on deep surface of submaxillary gland to base of 

 lower jaw, over which it ascends to face, being anterior tc 

 masseter muscle ; ascending to inner canthus, imbedded in 

 levator labii superioris alaeque nasi, where it takes name of 

 angular, it rests successively upon lower jaw, buccinator, and 

 levator anguli oris, with vein to outer side, and crossed by 

 platysma, risorius, zygomaticus major, and sometimes by the 

 levator labii superioris ; anas, ophthalmic
