| primitive perivisceral cavity | The space between the ectoderm and endoderm in the gastrula. Synonym: primitive perivisceral cavity. (05 Mar 2000) |

| primitive pit | The depression in the primitive node that serves to connect the notochordal canal with the surface ectoderm and the yolk sac. These connections are referred to as the neurenteric canal. (05 Mar 2000) |
| primitive reticular cell | A cell with processes making contact with those of other similar cell's to form a cellular network; along with the network of reticular fibres, the reticular cell's form the stroma of bone marrow and lymphatic tissues. (05 Mar 2000) |
| primitive ridge | One of the paired ridge's on either side of the primitive groove. (05 Mar 2000) |
| primitive streak | An ectodermal ridge in the midline at the caudal end of the embryonic disk from which arises the intraembryonic mesoderm; achieved by inward and then lateral migration of cells; in human embryos, it appears on day 15 and gives a cephalocaudal axis to the developing embryo. Synonym: germinal streak. (05 Mar 2000) |
| neuroectodermal tumour, primitive | A malignant brain tumour sharing common features and biologic properties with medulloblastoma. Some pathologists and clinicians use the terms interchangeably: they both can disseminate throughout the nervous system and, in some cases, systemically. most lesions arise from the posterior fossa in children under five years of age. The tumour often produces hydrocephalus and symptoms of increased intracranial pressure. Papilledema is often present. (12 Dec 1998) |
| pili, sex | Filamentous or elongated proteinaceous structures which extend from the cell surface in gram-negative bacteria that contain certain types of conjugative plasmid. These pili are the organs associated with genetic transfer and have essential roles in conjugation. Normally, only one or a few pili occur on a given donor cell. this preferred use of "pili" refers to the sexual appendage, to be distinguished from bacterial fimbriae (fimbriae, bacterial), also known as common pili, which are usually concerned with adhesion.

| heterogametic sex | <biology> The gender which has two different sex chromosomes. For example: In humans, the male is heterogametic because he is XY (has an X chromosome and a Y chromosome). In birds, the female is heterogametic because she is WZ (has a W chromosome and a Z chromosome). Compare: homogametic sex. (09 Oct 1997) |
| secondary sex characters | Those character's peculiar to the male or female that develop at puberty, e.g., the beard of men and the breasts of women. (05 Mar 2000) |
| homogametic sex | <genetics> The gender which has two copies of the same sex chromosome. For example: In humans, the female is homogametic because she is XX (has two copies of the X chromosome). In birds, the male is homogametic because he is ZZ (has two copies of the Z chromosome). Compare: heterogametic sex. (09 Oct 1997) |
| sex | 1. The distinguishing peculiarity of male or female in both animals and plants; the physical difference between male and female; the assemblage of properties or qualities by which male is distinguished from female. 2.

One of the groups founded on this distinction. The sex, the female sex; women, in general. Origin: L. Sexus: cf. F. Sexe. Source: Websters Dictionary (01 Mar 1998) |
