HEAD AND NECK. 



THE dissectors of the Head and Neck begin work as soon 

 as the subject is brought into the room. During the first 

 three days, whilst the body is in the lithotomy posture, they 

 dissect the face, the anterior part of the eyelids, the superficial 

 part of the nose, and the anterior part of the scalp. During 

 the following five days, when the body is lying on its back, 

 they dissect the posterior triangle, and complete the dissection 

 of the scalp. 



It is only by dissecting the face at this period, whilst 

 the parts are in good condition, that the dissector can 

 gain any satisfactory idea of its component parts ; and it is 

 essential that the contents of the posterior triangle, which 

 is such an important surgical region, should be displayed 

 before the dissector of the arm has disturbed its posterior 

 boundary. 



The first day should be devoted to the examination of the 

 anterior part of the frontal region of the head and the face, 

 the study of the surface anatomy of the ocular appendages, 

 the reflection of the skin and the cleaning of the superficial 

 muscles of the face and anterior part of the scalp. On the 

 second day the dissectors should display the superficial 

 surface of the parotid gland ; they should also find and 

 clean the superficial vessels and nerves, and trace them to
