8o ELEMENTS OF MAMMALIAN ANATOMY. 



The muscles of the following table are arranged accord- 

 ing to location, but they need not be dissected in the order 

 named. Some classes having time for the study of one- 

 half or even one-third of the muscles here described will 

 be able by the use of the table and the illustrations to become 

 familiar with the functions and the relations of any muscles 

 the instructor may wish to assign for study. The student 

 should note carefully the muscles which together effect a 

 certain motion, such as the flexion of the forearm or the 

 extension of the digits.
