| radiata | <zoology> An extensive artificial group of invertebrates, having all the parts arranged radially around the vertical axis of the body, and the various organs repeated symmetrically in each ray or spheromere. It includes the coelenterates and the echinoderms. Formerly, the group was supposed to be a natural one, and was considered one of the grand divisions of the animal kingdom. Origin: NL, fr. Radiatus, p. P. See Radiate. Source: Websters Dictionary (01 Mar 1998) |
| pars radiata lobuli corticalis renis | The centre of the renal lobule, which has the shape of a small, steep pyramid, consisting of straight tubular parts; these may be either ascending or descending limbs of the nephronic loop or collecting tubules. Synonym: pars radiata lobuli corticalis renis, Ferrein's pyramid, processus ferreini. (05 Mar 2000) |
| corona radiata | A fan-shaped fibre mass on the white matter of the cerebral cortex, composed of the widely radiating fibres of the internal capsule; a single layer of columnar cells derived from the cumulus oophorus, which anchor on the pellucid zone of the oocyte in a secondary follicle. Synonym: radiate crown. (05 Mar 2000) |
| ligamenta sternocostalia radiata | Fibres of the articular capsule that radiate from the costal cartilages to the anterior surface of the sternum. Synonym: ligamenta sternocostalia radiata. (05 Mar 2000) |
| zona | Origin: L, a girdle. See Zone. A zone or band; a layer. Zona pellucida. [NL. <biology> A radiately striated membrane situated next the yolk of an ovum, or separated from it by a very delicate membrane only. Source: Websters Dictionary (01 Mar 1998) |
| zona arcuata | The inner third of the basilar membrane of the cochlear duct extending from the tympanic lip of the osseous spiral lamina to the outer pillar cell of the spiral organ (of Corti). Synonym: zona arcuata, zona tecta. (05 Mar 2000) |
| zona ciliaris | The outer, wider zone of the anterior surface of the iris, separated from the pupillary zone by the collarette. Synonym: zona ciliaris. (05 Mar 2000) |
| zona corona | An irregularly disposed collection of visible veins seen in the skin of people usually of or past middle age; it has no specific connection with any deep structure, such as the diaphragm, and no necessary connection with underlying visceral disease. Synonym: zona corona. (05 Mar 2000) |

| zona facialis | Herpes zoster involving the face. (05 Mar 2000) |
| zona fasciculata | The wide middle zone of the adrenal cortex. This zone consists of large lipid-laden cells radially arranged in parallel cords. It converts pregnenolone to cortisol by a series of enzymatically regulated steps. A small amount of corticosterone is formed as a by-product of cortisol synthesis. (12 Dec 1998) |
| zona glomerulosa | The narrow subcapsular outer zone of the adrenal cortex. This zone consists of granular cells which stain deeply and are arranged in rounded groups. It converts pregnenolone to aldosterone by a series of enzymatically regulated steps. (12 Dec 1998) |
| zona haemorrhoidalis | The part of the anal canal that contains the rectal venous plexus. Synonym: annulus haemorrhoidalis, zona haemorrhoidalis. (05 Mar 2000) |
