68 THE POCKET ANATOMY 



Branches : 



Muscular to digastric, stylo-hyoid ; stcrno-mastoid branch to 

 supply that muscle. 



Mastoid : through mastoid foramen to dura mater. 



Posterior meningeal: ascends, in company with internal 

 jugular vein, through jugular foramen to dura mater in 

 posterior fossa. 



Cervical (ramus princess cervicis) : at outer border of corn- 

 plexus ; descends at back of neck ; superficial branch passes 

 beneath splenius, supplying it and the trapezius, anas. 

 superficial cervical ; deep branch, goes beneath complexus, 

 anas, vertebral, deep cervical of superior intercostal. 



Cranial : to muscles and integuments of occiput ; anas. 

 opposite fellow, posterior auricular and superficial tem- 

 poral. 



Posterior auricular : arises opposite apex of styloid process, 

 ascends in parotid to groove between pinna and mastoid pro- 

 cess, dividing into anterior or auricular, anas, posterior division 

 of temporal ; and. posterior or mastoid, anas, occipital. Joined 

 near mastoid process by posterior auricular branch of the 7th 

 nerve. 



Branches : 



Stylo-mastoid : enters stylo-mastoid foramen, supplying tym- 

 panum, mastoid cells, etc. 



Auricular : to posterior part of concha. 



Ascending branch of External Carotid : 



Ascending Pharyngeal : smallest branch, arising half an 

 inch above origin of trunk, ascends between internal carotid 

 and pharynx to base of skull. 



Branches : 



Prevertebral : to rectus anticus, ist cervical ganglion, and 

 gth, loth and nth nerves, glands, etc. 



Pharyngeal (three or four) : inwards to pharynx, supplying 

 constrictors, Eustachian tube, and a palatine branch to soft 

 palate and tonsil. 



Meningeal : one through foramen jugulare, another through 

 anterior condylar foramen, and a third through foramen 

 lacerum medium to supply dura mater. 



Terminal Branches of External Carotid : 



Superficial temporal : smaller of two terminal branches, 

 continues in the line of external carotid. Imbedded at first 

 in parotid, crosses over root of zygoma in -front of auriculo- 

 temporal nerve, upwards under skin fora inches, dividing intq 

 two terminal branches.
