Etymologies

Sorry, no etymologies found.

Examples

  • 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.

    Jonathan Wells gets everything wrong, again - The Panda's Thumb

  • 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 GREATEST SHOW ON EARTH

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

    Ancient history

  • 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.

    On Food and Cooking, The Science and Lore of the Kitchen

  • 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.

  • And said gillslits and myotomes are all to no avail.

    It's a Long Way From Amphioxus

  • 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.

    IV. Myology. 2. Development of the Muscles

  • The anterior vertebral muscles, the Longus colli, Longus capitis, Rectus capitis anterior and Rectus capitis lateralis are derived from the ventral part of the cervical myotomes as are probably also the Scaleni.

    IV. Myology. 2. Development of the Muscles

  • The shorter muscles, such as the Interspinales, Intertransversarii, the deeper layers of the Multifidus, the Rotatores, Levatores costarum, Obliquus capitis inferior, Obliquus capitis superior and Rectus capitis posterior minor which extend between adjoining vertebræ, retain the primitive segmentation of the myotomes.

    IV. Myology. 2. Development of the Muscles

  • —The intrinsic muscles of the trunk which are derived directly from the myotomes are conveniently treated in two groups, the deep muscles of the back and the thoraco-abdominal muscles.
