This metamerism is most distinct in the neck and trunkregions, and at first only in the dorsal portions of these 126 THE DEVELOPMENT OF THE HUMAN BODY. regions, the ventral portions showing metamerism onlyafter the extension into them of the myotomes. But thereis clear evidence that the arrangement extends also intothe head, and that this, like the rest of the body
