| telencephalic vesicle | Paired diverticula arising from the prosencephalon, from which the forebrain develops. (05 Mar 2000) |
|---|---|
| encephalic vesicle | Each of the three divisions of the early embryonic brain (prosencephalon, mesencephalon, and rhombencephalon). Synonym: encephalic vesicle, primary brain vesicle. (05 Mar 2000) |
| transcytotic vesicle | <cell biology> Membrane bounded vesicle that shuttles fluid from one side of the endothelium to the other. There is some controversy as to whether or not they form pores. (17 Mar 1998) |
| endocytic vesicle | The vesicle (membrane-bound bubble within the cell) which is formed during the process of endocytosis and which contains substances being imported from outside of the cell. (09 Oct 1997) |
| endocytotic vesicle | Uptake of material into a cell by the formation of a membrane bound vesicle. (18 Nov 1997) |
| transport vesicle | <cell biology> Vesicles that transfer material from the rough endoplasmic reticulum to the receiving face of the Golgi. (18 Nov 1997) |
| excretory duct of seminal vesicle | The passage leading from a seminal vesicle to the ejaculatory duct. Synonym: ductus excretorius vesiculae seminalis. (05 Mar 2000) |
| exocytotic vesicle | <cell biology> Vesicle, for example a secretory vesicle or zymogen granule, that can fuse with the plasma membrane to release its contents. (18 Nov 1997) |
| umbilical vesicle | <embryology, ornithology> One of the set of extra embryonic membranes, growing out from the gut over the yolk surface, in birds formed from the splanchnopleure, an outer layer of splanchnic mesoderm and an inner layer of endoderm. (18 Nov 1997) |
| forebrain vesicle | <anatomy> The anterior segment of the brain, including the cerebrum and olfactory lobes; the forebrain. The cerebrum. Origin: NL, fr. Gr. Toward, near to + E. Encephalon] [Sometimes abbreviated to proen. Source: Websters Dictionary (01 Mar 1998) |
| lens vesicle | In the embryo, the ectodermal invagination that forms opposite the optic cup; it is the primordium of the lens of the eye. Synonym: lenticular vesicle. (05 Mar 2000) |
| lenticular vesicle | In the embryo, the ectodermal invagination that forms opposite the optic cup; it is the primordium of the lens of the eye. Synonym: lenticular vesicle. (05 Mar 2000) |
| fusogenic vesicle | <cell biology> A liposome (artificially-created vesicle) whose outer wall contains molecules (such as the F protein) that cause cell fusion, especially fusion between somatic cells (any cell that is not a gamete). (09 Oct 1997) |
| receptors, cytoplasmic and nuclear | Proteins in the cytoplasm or nucleus that specifically bind signalling molecules and trigger changes which influence the behaviour of cells. The major groups are the steroid hormone receptors, which usually are found in the cytoplasm, and the thyroid hormone receptors, which usually are found in the nucleus. Receptors, unlike enzymes, generally do not catalyze chemical changes in their ligands. (12 Dec 1998) |
| Remak's nuclear division | <cell biology> An unusual form of nuclear division, in which the nucleus simply constricts, rather like a cell without chromosome condensation or spindle formation. Partitioning of daughter chromosomes is haphazard. Observed in some Protozoa. (18 Nov 1997) |
