| primordial | 1. First in order; primary; original; of earliest origin; as, primordial condition. "The primordial facts of our intelligent nature." 2. <geology> Of or pertaining to the lowest beds of the Silurian age, corresponding to the Acadian and Potsdam periods in American geology. It is called also Cambrian, and by many geologists is separated from the Silurian. 3. <biology> Originally or earliest formed in the growth of an individual or organ; as, a primordial leaf; a primordial cell. <botany> Primordial utricle, the interior lining of a young vegetable cell. Origin: L. Primordialis, from primordium the first beginning; primus first + ordiri to begin a web, to begin: cf. F. Primordial. Source: Websters Dictionary (01 Mar 1998) |

| primordial cartilage | Cartilage in an early stage in its development. (05 Mar 2000) |
| primordial cell | A cell from a group that constitutes the primordium of an organ or part of the embryo. (05 Mar 2000) |
| primordial cyst | A cyst which develops in place of a tooth through cystic degeneration of the enamel organ prior to formation of calcified odontogenic tissue. (05 Mar 2000) |
| primordial dwarfism | Dwarfism characterised by normal development that is at a strikingly lesser rate than that for members of the same family, race, or other races. Synonym: primordial dwarfism, true dwarfism. (05 Mar 2000) |
| primordial germ cell | The most primitive undifferentiated sex cell, found initially outside the gonad. Synonym: gonocyte. (05 Mar 2000) |
| primordial gigantism | Unusually large size from birth due to familial or genetic factors or intrauterine environment (e.g., maternal prediabetic state) and not to hyperpituitarism. (05 Mar 2000) |
| primordial kidney | 1. The definitive excretory organ of primitive fishes. Synonym: head kidney. 2. In the embryos of higher vertebrates, a vestigial structure consisting of a series of tortuous tubules emptying into the cloaca by way of the primary nephric duct; in the human embryo, the pronephros is a very rudimentary and temporary structure, followed by the mesonephros and still later by the metanephros. Synonym: forekidney, primordial kidney. Origin: pro-+ G. Nephros, kidney (05 Mar 2000) |
| primordial ovarian follicle | A follicle in which the primordial oocyte is surrounded by a single layer of flattened follicular cells. (05 Mar 2000) |
| alecithal ovum | An ovum in which the yolk is nearly absent, consisting of only a few particles. (05 Mar 2000) |
| blighted ovum | A fertilized ovum whose development has ceased at an early stage. (27 Sep 1997) |
| centrolecithal ovum | One in which the yolk is mostly located near the centre of the egg, as in arthropods. (05 Mar 2000) |
| Peters' ovum | An ovum with a presumptive fertilization age of about 13 days; for many years, it was one of very few young human embryos recovered in good condition and its study furnished many facts regarding early embryonic changes. (05 Mar 2000) |
| migration of ovum | <gynaecology> The transperitoneal passage of an ovum from the ovarian follicle into the uterine tube. (05 Mar 2000) |
| cleavage stage, ovum | The embryo in its earliest stage, lasting from the first mitotic division of the fertilised ovum into two blastomeres to the formation of the morula, a compact mass of blastomeres. (12 Dec 1998) |
| primordial ovum |
A germ cell that arises very early in the development of the embryo, usually in the yolk sac endoderm, migrates into the urogenital ridge, and is the precursor for the functional gamete.
