| venules | The minute vessels that collect blood from the capillary plexuses and join together to form veins. (12 Dec 1998) |
|---|---|
| pericytic venules | The microvasculature immediately following the capillaries, ranging in size from 10 to 50 um, and characterised by investment of pericytes; they are the site of extravasation of blood cells, are particularly sensitive to histamine, and are believed to be important in blood-interstitial fluid exchanges. Synonym: pericytic venules. (05 Mar 2000) |
| postcapillary venules | The microvasculature immediately following the capillaries, ranging in size from 10 to 50 um, and characterised by investment of pericytes; they are the site of extravasation of blood cells, are particularly sensitive to histamine, and are believed to be important in blood-interstitial fluid exchanges. Synonym: pericytic venules. (05 Mar 2000) |
| high endothelial postcapillary venules | Venule's in the lymph nodes, tonsils, and Peyer's patches that have a high-walled endothelium through which blood lymphocytes migrate into the lymphatic parenchyma. (05 Mar 2000) |
| nasal venules of retina | See: inferior nasal venule of retina, superior nasal venule of retina. (05 Mar 2000) |
| straight venules of kidney | Venules that drain the medullary pyramids of the kidney; they open into arcuate veins. Synonym: venulae rectae renis. (05 Mar 2000) |
| temporal venules of retina | See: inferior temporal venule of retina, superior temporal venule of retina. (05 Mar 2000) |
| stellate | Shaped like a star. (27 Sep 1997) |
| stellate abscess | A star-shaped necrotic area surrounded by histiocytes, seen within swollen inguinal lymph nodes in lymphogranuloma venereum. (05 Mar 2000) |
| stellate block | Injection of local anaesthetic solution in the vicinity of the stellate ganglion. (05 Mar 2000) |
| stellate breast lesions | <radiology> Scirrhous carcinoma (infiltrating ductal carcinoma), small (baby) scirrhous carcinoma, sclerosing ductal hyperplasia, traumatic fat necrosis, hyalinised fibroadenoma (12 Dec 1998) |
| stellate cataract | Congenital cataract with lens opacities radiating toward the periphery, with subcapsular and cortical changes. (05 Mar 2000) |
| stellate cells of cerebral cortex | Small star-shaped cell's in the second and fourth layers of the cortex, and large stellate cell's in the deeper part of the third layer in the visual cortex. (05 Mar 2000) |
| stellate cells of liver | Large star-shaped or pyramidal cells with a large oval nucleus and a small prominent nucleolus. These intensely phagocytic cells line the walls of the sinusoids of the liver and form a part of the reticuloendothelial system. (12 Dec 1998) |
| stellate fracture | A fracture in which the lines of break radiate from a central point. (05 Mar 2000) |
