    The Notch Signaling Pathway in Embryogenesis 

    Wolter, Justin (Arizona State University. School of Life Sciences. Center for Biology and Society. Embryo Project Encyclopedia., 2013-03-18)
    The Notch signaling pathway is a mechanism in animals by which adjacent cells communicate with each other, conveying spatial information and genetic instructions for the animal's development. All multicellular animals ...

    Hedgehog Signaling Pathway 

    Haskett, Dorothy R. (Arizona State University. School of Life Sciences. Center for Biology and Society. Embryo Project Encyclopedia., 2015-07-30)
    The hedgehog signaling pathway is a mechanism that directs the development of embryonic cells in animals, from invertebrates to vertebrates. The hedgehog signaling pathway is a system of genes and gene products, mostly ...

    Endoderm 

    MacCord, Kate (Arizona State University. School of Life Sciences. Center for Biology and Society. Embryo Project Encyclopedia., 2013-11-17)
    Endoderm is one of the germ layers-- aggregates of cells that organize early during embryonic life and from which all organs and tissues develop. All animals, with the exception of sponges, form either two or three germ ...

    Ectoderm 

    MacCord, Kate (Arizona State University. School of Life Sciences. Center for Biology and Society. Embryo Project Encyclopedia., 2013-12-03)
    Ectoderm is one of three germ layers--groups of cells that coalesce early during the embryonic life of all animals except maybe sponges, and from which organs and tissues form. As an embryo develops, a single fertilized ...

    Epithelium 

    MacCord, Kate (Arizona State University. School of Life Sciences. Center for Biology and Society. Embryo Project Encyclopedia., 2012-11-05)
    Frederik Ruysch, working in the Netherlands, introduced the term epithelia in the third volume of his Thesaurus Anatomicus in 1703. Ruysch created the term from the Greek epi, which means on top of, and thele, which means ...

    Temperature-Dependent Sex Determination in Reptiles 

    Moeller, Karla T. (Arizona State University. School of Life Sciences. Center for Biology and Society. Embryo Project Encyclopedia., 2013-03-18)
    The sex of a reptile embryo partly results from the production of sex hormones during development, and one process to produce those hormones depends on the temperature of the embryo's environment. The production of sex ...

    Human Evolution Inferred from Tooth Growth and Development 

    MacCord, Kate (Arizona State University. School of Life Sciences. Center for Biology and Society. Embryo Project Encyclopedia., 2013-04-05)
    To study human evolution, researchers sometimes use microstructures found in human teeth and their knowledge of the processes by which those structures grow. Human fetusus begin to develop teeth in utero. As teeth grow, ...

    The Process of Implantation of Embryos in Primates 

    Wolter, Justin M. (Arizona State University. School of Life Sciences. Center for Biology and Society. Embryo Project Encyclopedia., 2013-04-05)
    Implantation is a process in which a developing embryo, moving as a blastocyst through a uterus, makes contact with the uterine wall and remains attached to it until birth. The lining of the uterus (endometrium) prepares ...

    Biological Clocks and the Formation of Human Tooth Enamel 

    MacCord, Kate (Arizona State University. School of Life Sciences. Center for Biology and Society. Embryo Project Encyclopedia., 2013-03-18)
    Tooth enamel contains relics of its formation process, in the form of microstructures, which indicate the incremental way in which it forms. These microstructures, called cross-striations and striae of Retzius, develop as ...

    Dinosaur Egg Parataxonomy 

    Madison, Paige (Arizona State University. School of Life Sciences. Center for Biology and Society. Embryo Project Encyclopedia., 2015-03-23)
    Dinosaur egg parataxonomy is a classification system that organizes dinosaur eggs by descriptive features such as shape, size, and shell thickness. Though egg parataxonomy originated in the nineteenth century, Zi-Kui Zhao ...
