THE PULSE. 



^% 



The cut admirably shows the muscles, nerves, and blood- 

 vessels of the head and the upper part of the neck. "We 

 have reserved it to introduce here, in order to point out the 

 location of the pulse so plainly that no one can be at a loss 

 where to look for it. It will be easily found in the living 

 subject, at the point here indicated by lo. Down to p, inclu- 

 sive, the lettering below relates to the muscles. 



a The upper part of the ligsCment of the neck — the wUUeather. 



* The levator humeri (elevator of the 8houlder), arising from the tubercle of 

 the occiput, the mastoid (nipple-shaped) process of the temporal bone, 

 and the transverse processes (cross projections) of the first four 

 bones of the neck, and the ligament of the neck, and going to the 

 muscles of the shoulders and the upper bone of the arm : to draw 

 forward the shoulder and arm, or turn the head and neck; and, 

 when the two levators act, to depress the head. 



e The tendon common to the complexus major (larger complicated), and spleniua 

 (splint-like) ; to the mastoid process of the temporal bone, to hold up 

 the head, or, the muscles on one side alone acting, to turn it. 



d The stemo-maxillaris (belonging to the breast-bone) and upper jaw, from the 

 cartilage in front of the chest to the angle of the lower jaw; to bend 

 the head, or, if only one acts, to bend it on one side. 



e The stylo-mazillaris, from the styloid (pencil-shaped) or coracoid (beak- 

 shaped) process of the occiput, to the angles of the jaw : to pull the 

 jaw backward and open it.
