440 APPENDIX. 
(Fig. 65, 1 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, 4). 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 scapule ventralis (p. 120, and Fig. 72, c, c', ce” 
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, 7). Transect. 
7. The digastric (p. 107, and Fig. 65, 4). Transect, and reflect 
completely, to the origin and insertion. 
8. The mylohyoid (p. 114, and Fig. 65, c). Transect and 
reflect. 
g. The geniohyoid (p. 113, and Fig. 67, g). 
10. The jugulohyoid (p. 113, and Fig. 67, 4). 
(The extrinsic muscles of the tongue (p. 228, and Figs. 67 and 
96) may be dissected at this point, if desired. (2) The styloglossus ; 
(4) the genioglossus; (c) the hyoglossus, ‘They need not be cut.) 
11. The masseter (p. 108, and Fig. 65, 2). 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. 110, 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, 7) must be cut and reflected.
