| opening of superior vena cava | The point of entry of the superior vena cava into the right atrium. Synonym: ostium venae cavae superioris, orifice of superior vena cava. (05 Mar 2000) |
|---|---|
| orifice of superior vena cava | The point of entry of the superior vena cava into the right atrium. Synonym: ostium venae cavae superioris, orifice of superior vena cava. (05 Mar 2000) |
| ligament of left superior vena cava | The obliterated left common cardinal vein that extends from the left brachiocephalic vein to the oblique vein of the left atrium. (05 Mar 2000) |
| arteria pulmonalis | Origin, right ventricle of heart; distribution, it divides into the right pulmonary artery and the left pulmonary artery, which enter the corresponding lungs and branch along with the segmental bronchi. Synonym: truncus pulmonalis, arteria pulmonalis, pulmonary artery, venous artery. (05 Mar 2000) |
| arteria pulmonalis dextra | <anatomy, artery> The longer of the two terminal branches of the pulmonary trunk, it passes transversely across the mediastinum passing inferior to the aortic arch to enter the hilum of the right lung. Branches are distributed with the bronchi; frequent variations occurs. Typical branches to the superior lobe (rami lobi superioris ) are apical (ramus apicalis ), anterior ascending (rami anterior ascendens ), anterior descending (ramus anterior descendens ), posterior ascending (ramus posterior ascendens ), and posterior descending (ramus posterior descendens ); to the middle lobe (rami lobi medii ) are medial (ramus medialis ) and lateral (ramus lateralis ); and to the inferior lobe (rami lobi inferioris ) are superior (apical) branch of inferior lobe (ramus superior (apicalis) lobi inferioris ), and the anterior, lateral (lateralis), medial (medialis) and posterior basal branches (rami basalis). Synonym: arteria pulmonalis dextra. (05 Mar 2000) |
| bifurcatio trunci pulmonalis | The division of the pulmonary trunk into right and left pulmonary arteries. Synonym: bifurcatio trunci pulmonalis. (05 Mar 2000) |
| valva trunci pulmonalis | <anatomy, cardiology> The heart valve that divides the right ventricle and the pulmonary artery. The pulmonic valve opens when the right ventricle contracts allowing blood to flow into the pulmonary artery. The pulmonic valve on closure prohibits the backwash of unoxygenated blood into the right ventricle. The pulmonic valve has 3 valve cusps. (27 Sep 1997) |
| valvula semilunaris anterior valvae trunci pulmonalis | Anterior semilunar cusp of the pulmonary valve. (05 Mar 2000) |
| valvula semilunaris dextra valvae trunci pulmonalis | Right semilunar cusp of the pulmonary valve. (05 Mar 2000) |
| ramus apicalis lobi inferioris arteriae pulmonalis dextrae | <anatomy, artery> Branch (of the inferior lobar branch) of the right pulmonary artery serving the apical segment of the inferior lobe of the right lung. Synonym: ramus apicalis lobi inferioris arteriae pulmonalis dextrae. (05 Mar 2000) |
| ramus apicoposterior venae pulmonalis sinistrae superioris | <anatomy, vein> Drains apicoposterior bronchopulmonary segment of superior lobe of left lung. Synonym: ramus apicoposterior venae pulmonalis sinistrae superioris. (05 Mar 2000) |
| ramus lobi medii arteriae pulmonalis dextrae | Middle lobe branch of right pulmonary artery. See: middle lobe branch. (05 Mar 2000) |
| ramus lobi medii venae pulmonalis dextrae superioris | Middle lobe branch of right superior pulmonary vein. See: middle lobe branch. (05 Mar 2000) |
| ramus posterior venae pulmonalis dextrae superioris | <anatomy, vein> Drains posterior portion of superior lobe of right lung. Synonym: ramus posterior venae pulmonalis dextrae superioris. (05 Mar 2000) |
| pars basalis arteriae pulmonalis | See: right pulmonary artery, left pulmonary artery. (05 Mar 2000) |
