440 APPENDIX. 



(Fig. 65, i and 2) should be removed if this has not been done; also 

 the lymphatic glands (Fig. 65, 3). 



If the superficial muscles of the head have not been dissected and 

 are not to be, remove the skin from the side of the neck, head, and 

 face to the median dorsal line, removing the thin superficial muscles 

 with the skin. Remove also the parotid, submaxillary, and lym- 

 phatic glands (Fig. 65, 1,2, and 3), and cut through the ear-muscles 

 and the cartilaginous auditory meatus (under direction) and remove 

 the external ear. Clean fat, connective tissue, etc., from the surface 

 of the muscles of the thorax, neck, and head; then dissect as follows: 



1. The sternomastoid (p. 139, and Fig. 65, g}. Transect and 

 reflect it. 



2. The cleidomastoid (p. 120, and Fig. 65, h}. This has 

 already been transected; examine now its origin. 



Remove the large lymphatic gland beneath the sternomastoid and 

 close to the tympanic bulla, and clean the surface of the muscles in 

 this region. 



3. The levator scapulae ventralis (p. 120, and Fig. 72, c, c', c"). 

 This has already been cut; study now its origin. 



4. The sternohyoid (p. 140, and Fig. 65, e). In raising it begin 

 at the cranial end and take care not to injure the subjacent sterno- 

 thyroid (Fig. 65, g'}. Transect. 



5. The sternothyroid (p. 141, and Fig. 65, g'}. Transect. 



6. The stylohyoid (p. 112, and Fig. 65, d). Transect. 



7. The digastric (p. 107, and Fig. 65, b). Transect, and reflect 

 completely, to the origin and insertion. 



8. The mylohyoid (p. 114, and Fig. 65, c]. Transect and 

 reflect. 



9. The geniohyoid (p. 113, and Fig. 67, g]. 



10. The jugulohyoid (p. 113, and Fig. 67, 6). 



(The extrinsic muscles of the tongue (p. 228, and Figs. 67 and 

 96) may be dissected at this point, if desired, (a) The styloglossus; 

 (&) the genioglossus ; (c) the hyoglossus. They need not be cut. ) 



11. The masseter (p. 108, and Fig. 65, a). Cut the superficial 

 and middle layers near their insertions by incisions parallel to the 

 border of the jaw. Cut the deep layer near its origin. Look for the 

 origin of fibres of the temporal muscle from the inner surface of the 

 middle layer. 



12. The temporal (p. no, and Fig. 63, ). Clear its outer sur- 

 face completely. Cut the temporal fascia transversely and reflect it 

 toward the insertion of the muscle, with the superficial portion of the 

 muscle. Cut through the zygomatic arch at its two ends and remove 

 it, dissecting the fibres of the temporal free from their origin on its 

 inner surface. Then examine the insertion of the temporal. 



(The muscles of the pharynx (p. 232) may be dissected at this 

 point; for directions, see page 451.) 



13. The ceratohyoid (p. 115). To uncover this, the middle 

 constrictor of the pharynx (Fig. 67, /) must be cut and reflected.
