|---|---|---|---|
| 설명 | 여성의 난소에 생성되는 미수정체를 말함. 이러한 난자가 남자에서 생성되는 정자와 결합되면 새로운 하나의 생명체가 만들어지게 된다. 난자에는 정상적인 세포의 DNA숫자에 비해 반수정도인 22개의 보통염색체와 한 개의 성염색체를 가지고 있으며, 정자가 들어올 경우 완전한 세포로 변한다. 또한 난자에는 이런 수정된 개체가 정상적으로 자라고 분열할 수 있도록 필요한 영양분도 같이 가지고 있다(정자에는 이런 영양분이 없다). 난자는 난소의 난포에서 만들어지며, 이렇게 생성되는 과정은 여성의 월경과 밀접한 관계가 있다. |

| 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 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) |

| 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.
