From: Bulk elastic properties of chicken embryos during somitogenesis
a) Representative image of a chick embryo showing the average thickness and boundaries of the model subregions, constructed by averaging image planes obtained using two-photon microscopy. Subregions AO: area opaca; AP: area pellucida; ML: midline structures; and I: Intermediate region. b) Structural model of the embryo (not to scale) showing the notation for the model subregions. Refer to Table 1 for the average sizes and thicknesses derived from microscope images. The paper ring, which serves as a fixed boundary condition, has radius AO r .
