| to-and-fro sound | Doubling of an abnormal murmur usually in systole and diastole and formerly applied to pericardial rubs. (05 Mar 2000) |
|---|---|
| Jewett sound | A short straight sound for dilating the anterior urethra. (05 Mar 2000) |
| first heart sound | Occurs with ventricular systole and is mainly produced by closure of the atrioventricular valves. (05 Mar 2000) |
| fourth heart sound | The sound produced in late diastole in association with ventricular filling due to atrial systole and related to reduced ventricular compliance. It is a low frequency oscillation that may be normal at older ages owing to a physiologic decline in ventricular compliance but is nearly always abnormal at younger ages if it is of high intensity or palpable. It is common in ventricular hypertrophy, particularly with hypertension, and is almost invariable during acute myocardial infarction. Fourth heart sounds may arise from the right or left ventricle or both. Synonym: atrial sound. (05 Mar 2000) |
| friction sound | 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) |
| Le Fort sound | A curved sound threaded for a filiform bougie, used for dilation of urethral strictures in the male when small caliber or presence of false passages prevents safe passage of a standard sound or catheter. (05 Mar 2000) |
| papillomatosis, laryngeal | Warty growths on the vocal cords. most common in young children. Recurrences are, unfortunately, frequent. Remission may occur after several years. Papillomatosis of the larynx can be due to the baby contracting human papilloma virus (HPV) during birth through the vaginal canal from a mother with genital warts (which are due to HPV). Each year, about 300 infants are born with the virus on their vocal cords because of maternal transmission. (12 Dec 1998) |
| recurrent laryngeal nerve | <anatomy, nerve> A branch of a nerve (the vagus nerve) that comes down the neck and turns back ( recurs ) to supply the larynx (the voice box ). (12 Dec 1998) |
| granuloma, laryngeal | A polypoid granulomatous projection into the lumen of the larynx. (12 Dec 1998) |
| protective laryngeal reflex | Closure of the glottis to prevent entry of foreign substances into the respiratory tract. (05 Mar 2000) |
| subcutaneous bursa of the laryngeal prominence | The bursa located between the junction of the laminae of the thyroid cartilage and the skin. Synonym: bursa subcutanea prominentiae laryngeae, laryngeal bursa. (05 Mar 2000) |
| superior laryngeal artery | <anatomy, artery> Origin, superior thyroid; distribution, muscles and mucous membrane of larynx; anastomoses, cricothyroid branch of superior thyroid and terminal branches of inferior laryngeal. Synonym: arteria laryngea superior. (05 Mar 2000) |
| superior laryngeal cavity | The upper part of the laryngeal cavity from the superior aperture to the vestibular folds, bounded anteriorly by the epiglottis, laterally by themucosa overlying the quadrangular membranes and posteriorly by the mucosa overlying the arytenoid cartilages and arytenoideus muscle. Synonym: vestibulum laryngis, atrium glottidis, superior laryngeal cavity. (05 Mar 2000) |
| superior laryngeal nerve | <anatomy, nerve> A branch of the vagus nerve at the inferior ganglion; at the thyroid cartilage it divides into two branches; the internal laryngeal nerve, a sensory branch which supplies the mucous membrane of the larynx superior to the vocal folds, and the external laryngeal nerve, a motor branch which supplies the inferior pharyngeal constrictor and the cricothyroid muscle. Synonym: nervus laryngeus superior. (05 Mar 2000) |
| superior laryngeal vein | <anatomy, vein> Vein which accompanies the superior laryngeal artery and empties into the superior thyroid vein. Synonym: vena laryngea superior. (05 Mar 2000) |
