| arteria colica sinistra | <anatomy, artery> Origin, inferior mesenteric; distribution, descending colon and splenic flexure; anastomoses, middle colic, sigmoid. Synonym: arteria colica sinistra. (05 Mar 2000) |
|---|---|
| arteria coronaria sinistra | <anatomy, artery> Origin, left aortic sinus; distribution, it divides into two major branches, an anterior interventricular which descends in the anterior interventricular sulcus, and a circumflex branch which passes to the diaphragmatic surface of the left ventricle; gives atrial, ventricular, and atrioventricular branches. Synonym: arteria coronaria sinistra. (05 Mar 2000) |
| arteria gastrica sinistra | <anatomy, artery> Origin, coeliac; distribution, cardia of stomach at lesser curvature, abdominal part of the oesophagus, and, frequently, a portion of the left lobe of the liver via an aberrant left hepatic branch; anastomoses, oesophageal, right gastric. Synonym: arteria gastrica sinistra, coronary artery. (05 Mar 2000) |
| arteria gastro-omentalis sinistra | <anatomy, artery> Origin, splenic; distribution, greater curvature of stomach and greater omentum; anastomoses, right gastroepiploic and short gastric arteries. Synonym: arteria gastro-omentalis sinistra, arteria gastroepiploica sinistra, left gastro-omental artery. (05 Mar 2000) |
| auricula sinistra | The small conical projection from the left atrium of the heart. Synonym: auricula sinistra, left auricular appendage. (05 Mar 2000) |
| valva atrioventricularis sinistra | <anatomy, cardiology> The heart valve that divides the left atrium and left ventricle. During left atrial contraction, the mitral valve opens to allow blood to flow into the left ventricle. Upon closure, the mitral valve prohibits the regurgitation of blood back into the left atrium. The mitral valve is the only heart valve that has only 2 valve cusps (all others have 3). (13 Nov 1997) |
| valvula semilunaris sinistra valvae aortae | Left semilunar cusp of the aortic valve. (05 Mar 2000) |
| pericolitis sinistra | Inflammation of the connective tissues surrounding the sigmoid flexure, giving rise to symptoms, referable to the left iliac fossa, similar to those of perityphlitis in the right iliac fossa. Synonym: pericolitis sinistra. (05 Mar 2000) |
| hemicardia sinistra | Left side of the heart. (05 Mar 2000) |
| flexura coli sinistra | The bend at the junction of the transverse and descending colon. Synonym: flexura coli sinistra, splenic flexure. (05 Mar 2000) |
| vena anastomotica superior | <anatomy, vein> A large communicating vein between the superficial middle cerebral vein and the superior sagittal sinus; it passes upward from the lateral sulcus, often following the line of the central sulcus (Rolando's fissure). Synonym: vena anastomotica superior, Trolard's vein. (05 Mar 2000) |
| vena azygos minor superior | <anatomy, vein> Formed by the union of the fourth to seventh left posterior intercostal veins, passes along the side of the bodies of the fifth, sixth, and seventh thoracic vertebrae, then crosses the midline behind the aorta, oesophagus, and thoracic duct, and empties into the azygos vein, sometimes in common with the hemiazygos vein. Synonym: vena hemiazygos accessoria, vena azygos minor superior. (05 Mar 2000) |
| vena basalis superior | <anatomy, vein> Tributary to the common basal vein draining the lateral and anterior part of the inferior lobe of each lung. Synonym: vena basalis superior. (05 Mar 2000) |
| vena cava superior | superior vena cava Previous: vena cava filter, vena cava filters, vena cava inferior, vena caval foramenNext: vena cava, superior, venacavographyvena cava, superior The venous trunk which returns blood from the head, neck, upper extremities and chest. (12 Dec 1998) |
