    The Carapacial Ridge of Turtles 

    Caniglia, Guido (Arizona State University. School of Life Sciences. Center for Biology and Society. Embryo Project Encyclopedia., 2012-05-25)
    Two main elements characterize the skeletal morphology of turtles: the carapace and the plastron. For a turtle, the carapacial ridge begins in the embryo as a bulge posterior to the limbs but on both sides of the body. ...

    Mechanistic Realization of the Turtle Shell 

    Caniglia, Guido (Arizona State University. School of Life Sciences. Center for Biology and Society. Embryo Project Encyclopedia., 2012-05-25)
    Turtle morphology is unlike that of any other vertebrate. The uniqueness of the turtle's bodyplan is attributed to the manner in which the turtle's ribs are ensnared within its hard upper shell. The exact embryological and ...

    Multi-Fetal Pregnancy 

    DeRuiter, Corinne (Arizona State University. School of Life Sciences. Center for Biology and Society. Embryo Project Encyclopedia., 2012-05-25)
    In humans, multi-fetal pregnancy occurs when a mother carries more than one fetus during the pregnancy. The most common multi-fetal pregnancy is twins, but mothers have given birth to up to eight children (octuplets) from ...

    The Yale Embryo 

    Smith, Kaitlin (Arizona State University. School of Life Sciences. Center for Biology and Society. Embryo Project Encyclopedia., 2012-05-10)
    In 1934 a fourteen-day-old embryo was discovered during a postmortem examination and became famous for being the youngest known human embryo specimen at the time. The embryo was coined "the Yale Embryo," named after the ...

    Gastrulation in Mus musculus (common house mouse) 

    Wolter, Justin M. (Arizona State University. School of Life Sciences. Center for Biology and Society. Embryo Project Encyclopedia., 2012-11-05)
    As mice embryos develop, they undergo a stage of development called gastrulation. The hallmark of vertebrate gastrulation is the reorganization of the inner cell mass (ICM) into the three germ layers: ectoderm, mesoderm, ...
