| accretio cordis | Adhesion of the pericardium to adjacent extracardiac structures. (05 Mar 2000) |
|---|---|
| annulus fibrosus cordis | One of four fibrous rings that surround atrioventricular and arterial orifices of the heart, providing attachment for the valve leaflets and maintaining patency of the orifice. As part of the fibrous skeleton of the heart, the fibrous rings also provide origin and insertion for the myocardium. Synonym: annulus fibrosus cordis, annulus fibrosus, coronary tendon, fibrous ring, Lower's ring. (05 Mar 2000) |
| apex cordis | The blunt extremity of the heart formed by the left ventricle. See: apex beat. Synonym: apex cordis, vertex cordis. (05 Mar 2000) |
| ataxia cordis | <cardiology> A condition where there is disorganised electrical conduction in the atria, resulting in ineffective pumping of blood into the ventricle. Acronym: AF (02 Jan 1998) |
| atrium cordis | The upper chamber of each half of the heart. Synonym: atrium cordis, atrium. Left atrium of heart, atrium of the left side of the heart which receives the blood from the pulmonary veins. Synonym: atrium sinistrum cordis, atrium pulmonale. (05 Mar 2000) |
| atrium dextrum cordis | Right atrium, the atrium of the right side of the heart which receives the blood from the venae cavae and coronary sinus. Synonym: atrium dextrum cordis. (05 Mar 2000) |
| atrium sinistrum cordis | left atrium of heart |
| basis cordis | That part of the heart that lies opposite the apex, formed mainly by the left atrium but to a small extent by the posterior part of the right atrium; it is directed backward and to the right and is separated from the vertebral column by the oesophagus and aorta. Synonym: basis cordis. (05 Mar 2000) |
| bulbus cordis | A transitory dilation in the embryonic heart where the arterial trunk joins the ventral roots of the aortic arches. (05 Mar 2000) |
| capsula cordis | <anatomy> A double membranous sac which envelops and protects the heart. The layer in contact with the heart is referred to as the visceral layer, the outer layer in contact with surrounding organs is the parietal pericardium. In between the two layers is the pericardial space. (27 Sep 1997) |
| palpitatio cordis | Palpitation of the heart. (05 Mar 2000) |
| venae cordis anteriores | 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) |
| venae cordis minimae | Numerous small valveless venous channels that open directly into the chambers of the heart from the capillary bed in the cardiac wall, enabling a form of collateral circulation unique to the heart. Synonym: smallest cardiac veins, thebesian veins. (05 Mar 2000) |
| ventriculus cordis | One of the two lower chambers of the heart. Synonym: ventriculus cordis. (05 Mar 2000) |
| margo dexter cordis | The border between the sternocostal and diaphragmatic surfaces of the heart; it is fairly well defined in fixed hearts but is rounded and indefinite in the living heart. Synonym: margo dexter cordis, right margin of heart. (05 Mar 2000) |
