MUSCLES OF THE NECK AND TRUNK 435 



OCULAR REGION 



Eight muscles are lodyed within the orbit fur moving the eyelid and eye. 

 They are severally named from the otlices which they perform. 



MUSCLES OF THE TONGUE 



Ten muscles are attached to the os hyoides, or bone of the tongue, for the 

 purpose of moving it backwards and laterally, and also to serve as agents in 

 the various movements of the tongue. 



MUSCLES OF THE PHARYNX 



As THE MOUTH CONTRACTS to form the funnel-shaped tube which ends in 

 the oesophagus, the latter is clothed with several muscles, which aid in 

 driving the food backw^ards. These are the hyo-pharyngeus and palato- 

 pharyngeus and the three constrictors of the pharnyx. 



LARYNGEAL REGION 



The cartilages op the larynx are moved by seven pairs of small but 

 beautifully defined muscles, named after their attachments. 



PALATINE REGION 



Two muscles move the soft palate, the tensor palati and circumflexus 

 palati ; but they can only be made out by a careful dissection of these 

 parts. 



SUPERFICIAL MUSCLES OF THE NECK AND 

 TRUNK 



The muscles of the neck and trunk are so intimately blended together 

 by their several attachments that they must be examined together. It will 

 be impossible to describe moi-e than the superficial ones ; but the most 

 important being those which connect the trunk with the extremities, they 

 will be selected as more especially deserving attention.
