| fibrillary chorea | Continuous involuntary quivering or rippling of muscles at rest, caused by spontaneous, repetitive firing of groups of motor unit potentials. Synonym: fibrillary chorea, kymatism, Morvan's chorea. Origin: myo-+ G. Kyma, wave (05 Mar 2000) |
|---|---|
| laryngeal chorea | A spasmodic tic involving the muscles, resulting in an explosive manner of talking as in spasmotic dysphonia. (05 Mar 2000) |
| 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) |
| vena cordis magna | <anatomy, vein> Begins at the apex of the heart (where it anastomoses with the middle cardiac vein), runs first with the anterior interventricular artery as it ascends the anterior interventricular groove, then turns to the left as it approaches or reaches the coronary groove to run with the circumflex branch of the left coronary artery; it merges with the oblique vein of the left atrium to form the coronary sinus. Synonym: vena cordis magna, left coronary vein, vena cardiaca magna. (05 Mar 2000) |
| vena cordis media | <anatomy, vein> Begins at the apex of the heart (where it anastomoses with the great cardiac vein), and ascends within the posterior interventricular sulcus to the coronary sinus. Synonym: vena cordis media, inferior cardiac vein. (05 Mar 2000) |
