n8 SURGICAL APPLIED ANATOMY. [Chap. ix. 



one inch of the stem of a clay pipe was discovered 

 deeply embedded in the glandular substance. It was 

 removed, and the common carotid tied. The patient, 

 however, never rallied from the previous severe hae- 

 morrhages, and soon died. The autopsy showed that 

 the stem of the pipe, which had not been missed by 

 the patient, had divided the ascending pharyngeal 

 artery (St. Bart's Hosp. .Reports, 1876). 



CHAPTER IX. 



THE NECK. 



Surface anatomy. Bony points. The hyoid 

 bone is on a level with the fourth cervical vertebra, 

 while the cricoid cartilage is opposite the sixth. The 

 upper margin of the sternum is (during expiration) 

 on a level with the disc between the second and third 

 dorsal vertebrae. At the back of the neck there is a 

 slight depression in the middle line which descends 

 from the occipital protuberance, and lies between the 

 prominences formed by the trapezius and complexus 

 muscles of the two sides. At the upper part of this 

 depression the spine of the axis can be made out on 

 deep pressure. Below this, the bony ridge formed by 

 the spines of the third, fourth, fifth, and sixth cervical 

 vertebrae can be. felt, but the individual spines cannot 

 usually be distinguished. At the root of the neck the 

 spinous process of the vertebra prominens is generally 

 very obvious. The transverse process of the atlas may 

 be felt just below and in front of the tip of the mastoid 

 process. By deep pressure in the upper part of the 

 supraclavicular fossa, the transverse process of the 

 seventh cervical vertebra can be distinguished. If
