na is the auricularis magnus. Immediately behind the 

 ear is the posterior auricular of the facial, and, along the 

 posterior border of the mastoid is the occipitalis minor, 

 while farther back, about midway between the mastoid 

 and the inion, is the occipitalis major. 



Landmarks for the Bloodvessels.-The frontal 

 artery supplies the neighborhood of the glabella, the 

 supra-orbital emerges from the orbit at the same point as 

 the supra-orbital nerve, above referred to, viz., at the 

 junction of the inner and middle thirds of the supra- 

 orbital margin ; the superficial temporal ascends 'over the 

 zygoma to the side of the head, having the superficial tem- 

 poral vein behind and overlapping it, and the auriculo- 

 temporal nerve behind the vein, so that the order of these 

 structures in the region of the zygoma, from behind for- 

 wards, is nerve, vein, artery. The superficial temporal 

 divides into two branches, anterior and posterior, about 

 one and a half inches above the zygoma the anterior 

 division, in its forward sweep, lying about one and a quar- 

 ter inches above and behind the external angular process. 

 Deeper in the temporal fossa are the deep temporal vessels 

 from the internal maxillary, and the middle temporal 

 from the superficial temporal artery. Immediately behind 

 the meatus is the posterior auricular, while midway be- 

 tween the mastoid process and the inion is the occipital 

 . artery. 



The Veins of the scalp follow -the lines of the arteries, 

 with the exception of the supra-orbital and the frontal; the 

 latter, beginning about the level of the coronal suture, and 

 passing downwards along the inner canthus of the eye 

 under the name of the angular vein, continues over the 

 face as the facial ; whereas, the former drains the terri- 

 tory above the orbit and, communicating with the ophthal- 

 mic, empties into the frontal vein.
