myotomes

All vertebrates have a segmented body plan, but in adult mammals as opposed to embryos this is readily apparent only in the spinal region, where the vertebrae and the ribs, the blood vessels, muscle blocks myotomes and nerves all follow a pattern of modular repetition from front to back.

The pharyngula stage/phylotypic stage is the time when Hox gene expression is ordered and active, when organogenesis is ongoing, and when the hallmarks of chordate embryology, like segmental myotomes, a tailbud, and branchial arches are forming.

And he said, "Gill slits and myotomes are all to no avail."

In fish, by contrast, muscle fibers are arranged in sheets a fraction of an inch thick (“myotomes”), and each short fiber merges into very thin layers of connective tissue (“myosepta”), which are a loose mesh of collagen fibers that run from the backbone to the skin.

Fat storage cells are found primarily in a distinct layer under the skin, and then in the visible sheets of connective tissue that separate the myotomes.

The intrinsic muscles of the arm develop in situ from the mesoderm of the arm bud and probably do not receive cells or buds from the myotomes.
