| spongiae | <zoology> The grand division of the animal kingdom which includes the sponges. Synonym: Spongida, Spongiaria, Spongiozoa, and Porifera. In the Spongiae, the soft sarcode of the body is usually supported by a skeleton consisting of horny fibres, or of silleceous or calcareous spicules. The common sponges contain larger and smaller cavities and canals, and numerous small ampullae which which are lined with ciliated cells capable of taking in solid food. The outer surface usually has minute pores through which water enters, and large openings for its exit. Sponges produce eggs and spermatozoa, and the egg when fertilized undergoes segmentation to form a ciliated embryo. See: Sponge. Source: Websters Dictionary (01 Mar 1998) |
| spongiform | 1. Soft, and full of cavities; of an open, loose, pliable texture; as, a spongy excrescence; spongy earth; spongy cake; spongy bones. 2.

| spongiform encephalopathies | A group of diseases characterised by long incubation and fatal progressive course with characteristic spongiform degeneration of grey matter of the cortex. The two main human diseases are kuru and Creutzfeldt Jakob disease. Diseases such as scrapie, mink encephalopathy and bovine spongiform encephalopathy (BSE) are considered to be similar. Controversy still surround the causative agent, the two main theories being slow viruses or prions. See: Gerstmann Straussler Scheinker syndrome. (18 Nov 1997) |
| spongiform encephalopathy | An encephalopathy characterised by vacuolation within nerve and glial cells. (05 Mar 2000) |
| spongilla | <zoology> A genus of siliceous spongea found in fresh water. Origin: NL, dim. Of spongia a sponge. Source: Websters Dictionary (01 Mar 1998) |
| spongin | <physiology> The chemical basis of sponge tissue, a nitrogenous, hornlike substance which on decomposition with sulphuric acid yields leucin and glycocoll. Source: Websters Dictionary (01 Mar 1998) |
| spongio- | Sponge, sponglike, spongy. Origin: G. Spongia (05 Mar 2000) |
| spongioblast | Cell found in developing nervous system: gives rise to astrocytes and oligodendrocytes. (18 Nov 1997) |
| spongioblastoma | <tumour> 1. A glioma consisting of cells (elongated, spindle-shaped, and sometimes pleomorphic, with one or two fibrillary processes) that resemble the embryonic spongioblasts, occurring normally around the neural canal of the human embryo; it grows relatively slowly, usually originating in the brainstem, optic chiasm, or infundibulum, and infiltrates adjacent structures or causes compression of the third and fourth ventricle. Spongioblastomas were formerly subclassified as spongioblastoma polare and spongioblastoma unipolare. 2. Obsolete term for glioblastoma multiforme. Origin: spongioblast + G. -oma tumour (05 Mar 2000) |
| spongiocyte | Lipid droplet rich cells from the middle region of the cortex of the adrenal gland. (18 Nov 1997) |
| spongioid | Synonym: spongy. Origin: spongio-+ G. Eidos, resemblance (05 Mar 2000) |
| spongiole | <botany> A supposed spongelike expansion of the tip of a rootlet for absorbing water. Synonym: spongelet. Origin: L. Spongiola a rose gall, small roots, dim. Of spongia: cf. F. Spongiole. Source: Websters Dictionary (01 Mar 1998) |
| spongiolite | <paleontology> One of the microsporic siliceous spicules which occur abundantly in the texture of sponges, and are sometimes found fossil, as in flints. Origin: Gr. Sponge. Source: Websters Dictionary (01 Mar 1998) |
| spongiopilin | <medicine> A kind of cloth interwoven with small pieces of sponge and rendered waterproof on one side by a covering of rubber. When moistend with hot water it is used as a poultice. Origin: Gr, dim. Of a sponge + felt. Source: Websters Dictionary (01 Mar 1998) |
