11Yolk sac — Not all yolk has to do with birds’ eggs. Human embryos have a yolk sac, a membrane outside the embryo but connected by a tube (the yolk stalk) though the umbilical opening to the embryo’s midgut. The yolk sac serves as an early site for …
12Nodal signaling — is a signal transduction pathway that is important in pattern formation and differentiation during embryo development.[1] The nodal family of proteins, a subset of the transforming growth factor beta (TGFβ) superfamily, is responsible for… …
13Body cavity — Picture of Human body cavities dorsal body cavity to the left and ventral body cavity to the right. By the broadest definition, a body cavity is any fluid filled space in a multicellular organism. However, the term usually refers to the space… …

15Germ cell — Germ cells are progenitors of the gametes. These singled out cells move through the gut to the developing gonads and undergo mitotic proliferation followed by meiosis and differentiation into either eggs or sperm (mature gametes). Plants do not… …
16Ectoderm — One of the three primary germ cell layers (the other two being the mesoderm and endoderm) that make up the very early embryo. The ectoderm is the outermost of the three layers. It differentiates to give rise to many important tissues and… …

18blastoderm, blastoderma — The thin, disk shaped cell mass of a young embryo and its extraembryonic extensions over the surface of the yolk; when fully formed, all three primary germ layers (ectoderm, endoderm, and mesoderm) are present …

20Pluripotency — in the broad sense refers to having more than one potential outcome. In biological systems, this can refer either to cells or to biological compounds. From the Latin pluri=many, potent=power, capacity. A pluripotent cell can create all cell types …
