The various systems of muscles have now been considered, and it 

 merely remains to give tables indicating the general relations of the 

 various systems to each other and referring the various muscles to- 

 their proper segments. The muscles or their representatives belong- 

 ing to pre-mandibular arches, I will not include in the table, as they 

 have not been considered in the preceding pages. The first table 

 indicates the relations of the cranial muscles, the second those of the 

 muscles of the trunk, including under that term all the body posterior 

 to the head.
