| 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) |
|---|---|
| sperm-ovum interactions | Interactive processes between the ovum and the spermatozoon. (12 Dec 1998) |
| isolecithal ovum | An ovum in which the yolk is evenly distributed throughout the cytoplasm. (05 Mar 2000) |
| ovum | 1. The female reproductive cell which, after fertilization, develops into a new member of the same species (von Baer, 1827), an egg. 2. The human ovum: a round cell about 0.1 mm. In diameter, produced in the ovary, where there is deposited around it a noncellular covering (oolemma, zona pellucida, zona radiata). It consists of protoplasm which contains some yolk, enclosed by a thin cell wall (vitelline membrane). There is a large nucleus (germinal vesicle), within which is a nucleolus (germinal spot). By extension, the word is also used to designate any early stage of the conceptus, when the embryo itself constitutes a tiny and insignificant part of the whole. (18 Nov 1997) |
| ovum implantation | Endometrial implantation of the blastocyst. (12 Dec 1998) |
| ovum implantation, delayed | Delay of embryonal development whereby the blastocyst remains in the uterine cavity for a variable period of time before attaching to the endometrium and continuing its development. (12 Dec 1998) |
| ovum transport | Transport of the ovum or zygote from the site of ovulation to the site of implantation. (12 Dec 1998) |
| telolecithal ovum | An ovum in which there is a large amount of yolk massed at the vegetative pole, as in the eggs of birds and reptiles. (05 Mar 2000) |
| epithelial migration | Apical shift of epithelial attachment, exposing more of the tooth crown. (05 Mar 2000) |
| fertilised ovum | An ovum impregnated by a spermatozoon. (05 Mar 2000) |
| foreign-body migration | Migration of a foreign body from its original location to some other location in the body. (12 Dec 1998) |
| leukocyte migration-inhibitory factors | Protein factor(s) released by sensitised lymphocytes (and possibly other cells) that inhibit the movement of leukocytes, especially polymorphonuclear cells, away from their site of release. Assays for these factors are used as tests for cellular immunity. Two of the common assays are the leukocyte migration capillary tube technique (lmct) and the leukocyte migration agarose technique (lmat). (12 Dec 1998) |
| abdominal external oblique muscle | <anatomy, muscle> Origin, fifth to twelfth ribs; insertion, anterior half of lateral lip of iliac crest, inguinal ligament, and anterior layer of the rectus sheath; action, diminishes capacity of abdomen, draws thorax downward; nerve supply, thoracoabdominal nerves. Synonym: musculus obliquus externus abdominis, abdominal external oblique muscle. (05 Mar 2000) |
| ambiguous external genitalia | External genitalia not clearly of either sex; most commonly designates external genitalia that are incompletely masculinised. (05 Mar 2000) |
| anterior scrotal branch of external pudendal artery | <anatomy, artery> Distribution, skin of anterior scrotum; anastomoses, posterior scrotal branches from internal pudendal artery. Synonym: rami scrotales anteriores arteriae pudendae externae. (05 Mar 2000) |
