| endothelium | <pathology> The layer of epithelial cells that lines the cavities of the heart and of the blood and lymph vessels and the serous cavities of the body, originating from the mesoderm. Origin: Gr. Thel = nipple (18 Nov 1997) |

| endothelium camerae anterioris | A single layer of large, squamous cells that covers the posterior surface of the cornea. Synonym: endothelium camerae anterioris. (05 Mar 2000) |
| endothelium, corneal | Single layer of large flattened cells covering the surface of the cornea. (12 Dec 1998) |
| endothelium-derived growth factor synthase | <enzyme> Converts l-arginine to a smooth muscle relaxing factor and stimulates the formation of cyclic-GMP Registry number: EC 1.5.1.- Synonym: edrf synthase (26 Jun 1999) |
| endothelium derived relaxation factor | <biochemistry> This compound is produced from L arginine by the enzyme nitric oxide synthase. Acts as a potent vasorelaxant via elevation of intracellular cGMP in vascular smooth muscle. Synthesis of nitric oxide is not confined to endothelium, isoforms of nitric oxide synthase are also found in brain, neutrophils and platelets. Synonym: endothelium derived relaxation factor. Acronym: NO (29 Dec 1997) |
| endothelium-derived relaxing factor | A labile humoral agent released by the vascular endothelium that mediates the relaxation induced by some vasodilators such as acetylcholine and bradykinin. Edrf also inhibits platelet aggregation, induces disaggregation of aggregated platelets, and inhibits platelet adhesion to the vascular endothelium. These actions are believed to be mediated through stimulation of guanylate cyclase and the consequent elevation of cyclic guanosine 3',5'-monophosphate. Edrf is thought to be nitric oxide or a ready source of it. The factor is believed to be unstable and acts only locally in vivo. (12 Dec 1998) |
| endothelium, lymphatic | Unbroken cellular lining (intima) of the lymph vessels (e.g., the high endothelial lymphatic venules). It is more permeable than vascular endothelium, lacking selective absorption and functioning mainly to remove plasma proteins that have filtered through the capillaries into the tissue spaces. (12 Dec 1998) |
| endothelium of anterior chamber | A single layer of large, squamous cells that covers the posterior surface of the cornea. Synonym: endothelium camerae anterioris. (05 Mar 2000) |
| endothelium, vascular | Single pavement layer of cells which line the luminal surface of the entire vascular system and regulate the transport of macromolecules and blood components from interstitium to lumen; this function has been most intensively studied in the blood capillaries. (12 Dec 1998) |
| anastomotic veins | See: inferior anastomotic vein, superior anastomotic vein. (05 Mar 2000) |
| anonymous veins | An obsolete term for brachiocephalic veins. (05 Mar 2000) |
| anterior cardiac veins | Two or three small veins in the anterior wall of the right ventricle opening directly into the right atrium independently of the coronary sinus. Synonym: venae cordis anteriores. (05 Mar 2000) |
| anterior cardinal veins | See: cardinal veins. (05 Mar 2000) |
| anterior intercostal veins | Tributaries to the musculophrenic or internal thoracic veins from the anterior portions of intercostal spaces. Synonym: venae intercostales anteriores. (05 Mar 2000) |
| anterior labial veins | Tributaries of the femoral or external pudendal veins draining the mons pubis and anterior labia majora. Synonym: venae labiales anteriores. (05 Mar 2000) |
