Figure 13

Striated body-wall muscle cells shown by position in the four muscle quadrants. The diagram is designed to show an animal as it would look cut along the dorsal midline and splayed out laterally. Colors represent lineal origin: (Red) Embryonic C lineage; (blue) embryonic MS lineage; (purple) embryonic AB lineage; (green) embryonic D lineage. Yellow cells are derivatives of the M mesoblast that are born postembryonically. (Redrawn, with permission, from Sulston and Horvitz 1977; Sulston et al. 1983.)
