| Ruysch's muscle | <anatomy> The muscular tissue of the fundus of the uterus. (05 Mar 2000) |
| Ruysch's tube | A minute tubular cavity opening in the lower and anterior portion of each surface of the nasal septum; best seen in the early foetal period when it is associated with the vomeronasal organ (Jacobson's organ). (05 Mar 2000) |
| Ruysch's veins | Portacaval anastomoses formed from vein's in the walls of retroperitoneal viscera, such as the ascending and descending colon, passing to the tributaries of the inferior vena cava in the posterior body wall instead of those of the portal vein. Synonym: Ruysch's veins. (05 Mar 2000) |
| malpighian glomerulus | <anatomy, nephrology> One of the structures which comprise the nephron (functional unit) in the kidney. The glomerulus is composed of capillary blood vessels which are actively involved in the filtration of the blood. (27 Sep 1997) |

| glomerulus of mesonephros | One of the tufts of capillary vessels within the mesonephros derived from a lateral branch of the primary aorta; each glomerulus is connected to a tubule. (05 Mar 2000) |
| glomerulus of pronephros | One of the tufts of capillary vessels in the pronephros derived from a lateral branch of the aorta. (05 Mar 2000) |
| olfactory glomerulus | One of the small spherical territories in the olfactory bulb in which dendrites of mitral and tufted cells synapse with axons of olfactory receptor cells. (05 Mar 2000) |
| juxtamedullary glomerulus | A glomerulus close to the medullary border. (05 Mar 2000) |
| kidney glomerulus | Globular tufts of capillaries, one projecting into the expanded end or capsule of each of the uriniferous tubules, which together with its surrounding capsule (glomerular capsule) constitute the renal corpuscle. (12 Dec 1998) |
| adamantine membrane | The primary enamel cuticle, consisting of two extremely thin layers (the inner one clear and structureless, the outer one cellular), covering the entire crown of newly erupted teeth and subsequently abraded by mastication; it is evident microscopically as an amorphous material between the attachment epithelium and the tooth. Synonym: cuticula dentis, adamantine membrane, dental cuticle, membrana adamantina, Nasmyth's cuticle, Nasmyth's membrane, skin of teeth. (05 Mar 2000) |
| allantoid membrane | An embryonic diverticulum of the hindgut of reptiles, birds, and mammals; in man its blood vessels give rise to those of the umbilical cord. (12 Dec 1998) |
| alveolocapillary membrane | The pulmonary diffusion barrier. (05 Mar 2000) |
