| 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) |

| bronchial fremitus | Adventitious pulmonary sounds or voice sounds perceptible to the hand resting on the chest, as well as by the ear. (05 Mar 2000) |
| vocal fremitus | The vibration in the chest wall, felt on palpation, produced by the spoken voice. (05 Mar 2000) |
| pericardial fremitus | Vibration in the chest wall produced by the friction of opposing roughened surfaces of the pericardium. See: pericardial rub. (05 Mar 2000) |
| rhonchal fremitus | Fremitus produced by vibrations from the passage of air in the bronchial tubes partially obstructed by mucous secretion. (05 Mar 2000) |
| pleural fremitus | Vibration in the chest wall produced by a friction rub resulting from the rubbing together of the roughened inflamed opposing surfaces of the pleura. (05 Mar 2000) |
| hydatid fremitus | The peculiar trembling or vibratory sensation felt on palpation of a hydatid cyst. Synonym: Blatin's syndrome, hydatid fremitus. (05 Mar 2000) |
