FIG. II. 



(THE SAME.) 



IN the goose all the muscles concerned in the motion of the jaws for mastication, 

 as well as the delicate mylo-hyoideal, and a thin square muscle arising from the side 

 of the lower jaw, and inserted into the hyoid bone, are supplied by the fifth ; and for 

 this reason the latter muscle ought to be compared with the maxillary portion of the 

 digastric in man. A muscle arising from the head and inserted into the angle of the 

 jaw, and compared with the upper belly of the digastric, and another analogous to the 

 stylo-hyoideal, arising from the lower jaw, and inserted into the side of the hyoid bone, 

 are supplied by the hard portion of the seventh, which also communicates with the 

 cervical nerves given to the cutaneous muscle of the face and neck. The long muscle 

 on the side of the trachea, the hyo-laryngeal, the trachea, the hyo-glossal, and lingual, 

 are supplied by the ninth ; another muscle arising from the lower jaw, and connected 

 with the posterior part of the hyoid bone, is supplied by the glosso-pharyngeal, whilst 

 the rest of this nerve terminates on the surface of the tongue, reaching as far as the tip. 

 The following muscles have been denominated according to the supply of corresponding 

 nerves in mammalia. 



a. Mylo-hyoideal muscle, b. Maxillary portion of the digastric muscle, c. Su- 

 perior portion of the digastric muscle, d. A muscle that may be compared 

 with the stylo-hyoideal. e. Cerato-maxillary muscle, arising from the lower 

 jaw, and then surrounding the cornu of the hyoid bone. f. Hyo-glossal 

 muscle, g. Lingual muscles, h. Hyo-laryngeal, or tracheal muscle. 



1. Branch of the third trunk of the fifth to the mylo-hyoideal muscle, and another 

 muscle, arising from the side of the lower jaw, and inserted into the hyoid 

 bone ; this muscle is analogous to the maxillary portion of the digastric.
