men, of that name, and, ascending vertically over the fore- 

 head, is distributed to the integument of this region and 

 the anterior portion of the scalp. 



The Frontal and Supra-orbital Arteries. Fig. 3. 



The first is one of the terminal branches of the ophthal- 

 mic, the second a branch also from the ophthalmic. 



The frontal accompanies the supratrochlear nerve (see 

 above) ; the supra-orbital the nerve of the same name 

 through the supra-orbital foramen to the distribution of 

 that nerve. 



The former artery anastomoses with the opposite frontal 

 and the supra-orbital arteries, the latter with the frontal and 

 anterior branch of the temporal. 



The Temporal Artery. Figs. 2 and 3. 



This is the external branch of bifurcation of the external 

 carotid. It starts under the parotid gland at the neck of 

 the lower jaw, passes upward and over the zygoma, and 

 divides into the anterior and posterior temporal branches. 

 These are distributed to the anterior, lateral, and posterior 

 portions of the head. The anterior anastomoses in front 

 with the frontal and supra-orbital ; the posterior, with the 

 posterior auricular and occipital arteries ; and both, over 

 the top of the head, with the corresponding arteries of the 

 other side, and in the lateral region with each other. For 

 remaining branches see page 62. 



Temporal Branches of the Facial, and Auriculotem- 

 poral Branch of the Fifth Nerves. Figs. 2, 3. 



For the former see the facial nerve, page 61. 



The auriculotemporal branch of the fifth nerve is found 

 (at a later stage of the dissection, see page 1 1 7) to arise by 

 two roots trunks, which surround the middle meningeal
