| coelom | <biology, embryology> An internal fluid-filled body cavity (other than the gut) within an organism, it lies between the gut (derived from the endoderm) and the outer body wall (derived from the ectoderm) and is lined entirely with tissue derived from the mesoderm. It is formed from the mesoderm during embryonic development. It is found in triploblastic animals called coelomates. (09 Oct 1997) |
|---|---|
| extraembryonic | Outside the embryonic body; e.g., those membranes involved with the embryo's protection and nutrition which are discarded at birth without being incorporated in its body. (05 Mar 2000) |
| extraembryonic blastoderm | That part of the blastoderm which is not incorporated in the embryo but forms membranes concerned in its nourishment and protection. (05 Mar 2000) |
| extraembryonic celom | That portion of the celom that extends beyond the confines of the embryonic body. (05 Mar 2000) |
| extraembryonic ectoderm | Derivative of epiblast outside the embryo's body. (05 Mar 2000) |
| extraembryonic membrane | A structure or tissue that develops from the fertilised ovum but does not form part of the embryo proper. Synonym: embryonic membrane, extraembryonic membrane. (05 Mar 2000) |
| extraembryonic mesoderm | Extraembryonic ectoderm cells or tissues which, though derived from the zygote, are not part of the embryo proper and along with the extraembryonic mesoderm form the foetal membranes (e.g., amnion). Synonym: primary mesoderm. (05 Mar 2000) |
| extraembryonic coelom |
the portion of the coelom external to the embryo, bordered by chorionic mesoderm and the mesoderm of the amnion and yolk sac; it communicates temporarily at the umbilicus with the intraembryonic coelom. Called also exocoelom.
