)f the posterior auricular artery, and in the external acoustic meatus with branches of the 

 nternal maxillary artery. 



(d) Transverse Facial. A branch of moderate size which emerges from under cover 

 Df the upper part of the anterior border of the parotid gland. It runs forwards across the 

 nasseter, below the zygoma and above the parotid duct, accompanied by zygomatic 

 oranches of the facial nerve, which may lie either above or below it. It supplies the 

 aarotid gland, the masseter, parotid duct, and the skin, and it terminates in branches 

 arhich anastomose with the infra-orbital and buccinator branches of the internal maxillary 

 irtery and with the buccal and masseteric branches of the external maxillary artery. 



(e) Middle Temporal. A branch which usually springs from the commencement of the 

 superficial temporal. It crosses the zygoma, pierces the temporal fascia and the temporal

(/) Zygomatico-orbital. This branch may spring directly from the superficial temporal, 



t is frequently a branch of the middle temporal. It runs anteriorly, above the 



oma, between the two layers of the temporal fascia. It supplies branches to the orbi- 



:ularis oculi, and anastomoses, through the zygomatic bone and round the outer margin 



the orbit, with the lacrimal and palpebral branches of the ophthalmic artery. 



The frontal branch runs forwards and upwards, in a tortuous course, through the 



rficial fascia of the scalp towards the frontal tuberosity, lying at first upon the temporal 



icia, and then upon the galea aponeurotica. It supplies the frontalis and the orbicularis 



, and anastomoses with the lacrimal and supra-orbital branches of the oph- 



lalmic artery, with the parietal terminal branch of the superficial temporal, and with its 



s ellow of the opposite side. 



The parietal branch, less tortuous than the frontal, runs upwards and posteriorly 



5 superficial fascia of the scalp. It anastomoses, anteriorly, with the frontal terminal 



-anch, posteriorly with the posterior auricular and occipital arteries, and, across the
