ARTERIES 69 



Branches : 



Parotid to gland. 



Transverse facial : arises in parotid, accompanies transverse 

 branches of facial nerve and parotid duct across face, lies 

 above the duct, supplying muscles, glands, etc. ; anas, facial, 

 infra-orbital. 



Middle temporal : arises just above zygoma, perforates tem- 

 poral fascia, supplying muscle ; anas, deep temporal. 



Orbital (may come from middle temporal) : along zygoma 

 between layers of temporal fascia to outer can thus. 



Anterior auricular : to anterior portion of external ear ; anas. 

 posterior auricular. 



A nterior temporal : one of terminal branches, ascends over tero - 

 poralfascia, supplying muscles, etc.; anas, frontal, supra- orbital. 



Posterior temporal: curves backwards over temporal fascia 

 and inosculates with opposite fellow; anas, posterior auricular, 

 occipital. 



Internal maxillary : larger of terminal branches, arises in 

 parotid, at first (maxillary portion) curving forwards between 

 jaw and internal lateral ligament, parallel with auriculo- 

 temporal nerve and lying on internal pterygoid muscle and 

 inferior dental nerve, then (pterygoid portion) forwards and 

 outwards on outer (frequently on inner) surface of lower head 

 of external pterygoid, finally (spheno - maxillary portion) 

 enters spheno-maxillary fossa between two heads of origin 

 of external pterygoid. 



Branches from Maxillary portion : 



Tympanic : enters Glaserian fissure, supplies tympanum, 

 and membrana tympani, generally gives off deep auricular to 

 external auditory meatus ; anas, vidian, stylo-mastoid. (May 

 come from middle meningeal.) 



Middle or great meningeal : arises between internal lateral 

 ligament and neck of conclyle, passes between two roots of 

 auriculo-temporal nerve, through foramen spinosum of the 

 sphenoid, dividing on great wing of sphenoid into anterior and 

 posterior branches ; anterior going to anterior inferior angle of 

 parietal, posterior to squamous of temporal ; anas, opposite 

 fellow, anterior and posterior meningeal. The trunk of the 

 artery gives off Gasserian, to ganglion. Petrosal : enters 

 hiatus Fallopii ; anas, stylo-mastoid of posterior auricular. 

 Orbital : through sphenoidal fissure to orbit. Temporal : 

 through foramen in bone to join branches from deep temporal. 



Small meningeal : through foramen ovale, supplies Gasserian 

 ganglion and dura mater. (Generally a branch of the middle 

 meningeal.)
