The Vertebrate as a Dual Animal: Somatic and Visceral "'In many regards the vertebrate organism, whether fish or  mammal, is a well-knit unit structure. But in  other respects there seems to be a  somewhat imperfect welding, functionally and structurally, of  two somewhat distinct beings: (1) an external, 'somatic,' animal, including most of the flesh and bone of our body, with a well organized nervous system and sense organs, in charge, so  to  speak, of 'external affairs,' and (2) an internal, 'visceral,' animal, basically consisting of the  digestive tract and its  appendages, which, to a considerable degree, conducts its own affairs, and over which the somatic animal exerts but incomplete control.'
