BLOOD-VESSELS OF THE HEAD.

The superior pharyngeal, m ptery go-palatine, is sometimes 

 a branch of the latter, and supplies the upper part of the 

 pharynx and Eustachian tube. The spheno-palatine, or 

 nasal, is the terminating trunk of the internal maxillary, 

 and passes along with the nerve of the same name, through 

 the spheno-palatine foramen, into the nose, where it divides 

 into two branches one going to the septum, the other to 

 the middle and lower turbinated bones, and their mucous 

 membrane.

All these vessels have been described under the respect- 

 ive heads of Blood-vessels of the Brain and Eye, which see. 

 The veins, corresponding to the branches of the external 

 carotid, have both a similar course and name, so that a 

 repetition would be unnecessary here. 



SECTION IV. 

 TABLE OF MUSCLES OF THE HEAD. 



According to the arrangement of Mr. Harrison, these 

 muscles are classed in accordance with the part upon which 

 they chiefly act. Six classes are made, embracing thirty- 

 six pair, and two single muscles. 



FIRST CLASS one muscle, 

 The muscle of the Scalp, or Occipito- 

 Frontalis. 



SECOND CLASS eleven muscles, 

 Those of the Ear, which are arranged 

 iuto three groups.
