 Blood Supply Of Pericardium | Pericardiacophrenic Artery-branch of internal thoracic A. May run together with phrenic nerve. |
| Nerve supply of pericardium | Phrenic nerves (C3-C5). Sensory innervation. Sympathetic trunks-vasomotor. |
| pericarditis | inflammation of pericardium. Causes pericardial friction rub, sonds like silk. |
| Pericardial effusion | fluid passes into the pericardial cavity. |
| Cardiac Tamponade | Heart compression. Fibrous pericardium is not elastic. Must do pericardiocentesis to reloeve pressure. |
| Surfaces of heart | Apex-tip of let ventricle. where mitral valve (apex)beat is loudest. Posterior aspect-left atrium Anterior surface-right ventrical Diaphragmatic surface-left ventrical left pulmonary surface-left ventricle right pulmonary surface-right atrium |
| RIght auricle | increases capacity of atrium |
| Coronary sinus | Receives blood from coronary veins |
| sinus venarum | smooth part of right atrium |
| Sulcus terminalis | external groove separating right auricle from right atrium |
| Crista terminalis | crest that extends internally from SVC to IVC. |
| Pectinate muscles | stringy muscles of atrium |
| Right AV (tricuspid) orifice | blood flows from R atrium to R ventricle |
| oval fossa | depression that is remnant of oval foramen. |
| conus arteriosis | smooth. leads to pulmonary trunk |
| trabeculae carneae | thin stringy muscles on surface of ventricle. |
| Cordae tendinae | strings attached to valves and papillary muscles. |
| moderator band | attaches papillary muscle to interventricular septum. carries right bundle branch |
| interventricular septum | muscle wall between left and right ventricles |
| papillary muscle | three in right ventricle, two in left ventricle. |
| mitral valve | left atrioventricular valve. bicuspid. |
| Stenosis | failure of valve to open fully |
| regurgitation | failure of valve to close properly |
| coronary arteries | R and L arise from sinuses of aortic valve |
