| pericardial friction sound | A to-and-fro grating, rasping, or, rarely, creaking sound heard over the heart in some cases of pericarditis, due to rubbing of the inflamed pericardial surfaces as the heart contracts and relaxes; during normal sinus rhythm it is usually triphasic; during any rhythm it may be biphasic or uniphasic. Synonym: pericardial rub, pericardial friction rub. (05 Mar 2000) |
| pleural friction rub | Friction rub sound caused by inflammation of the pleura. Synonym: pleural friction rub, pleural rale. (05 Mar 2000) |
| starting friction | The force that must be overcome to initiate the motion of one body relative to another because they have been resting in contact. Compare: dynamic friction. Synonym: static friction. (05 Mar 2000) |
| static friction | The force that must be overcome to initiate the motion of one body relative to another because they have been resting in contact. Compare: dynamic friction. Synonym: static friction. (05 Mar 2000) |
| dynamic friction | The force that must be overcome to maintain steady motion of one body relative to another because they remain in contact. Compare: starting friction. (05 Mar 2000) |
| friction | Surface resistance to the relative motion of one body against the rubbing, sliding, rolling, or flowing of another with which it is in contact. (12 Dec 1998) |
| friction murmur | The sound, heard on auscultation, made by the rubbing of two opposed serous surfaces roughened by an inflammatory exudate, or, if chronic, by nonadhesive fibrosis. Synonym: friction murmur, friction rub. (05 Mar 2000) |
