 males and in the spring of the year. See Parotiditis.

Murmur (nier'-mer) [L., a murmur]. A mimetic 

 name for the sounds heard on auscultation,

 gliding surfaces in the organs of circulation and respira- 

 tion. See Bruit. M., Accidental. See M., Hemic. 

 M., Anemic. See M., Hemic. M., Aneurysmal, the 

 aneurysmal bruit. See Bruit. M., Aortic, one

 aurium. Synonym of Tinnitus aurium. M., Bel- 

 lows, the bruit de sauffet, heard in cardiac hypertro- 

 phy and in mitral insufficiency. M., Blood. See M., 

 Hemic. M., Brain, a systolic sound heard over the 

 anterior fontanel, especially in young rickety children. 

 M., Cardiac, any one of those adventitious sounds 

 produced by the abnormal passage of blood through the 

 cavities and orifices of the heart or by perverted cardiac 

 action. The names given to these murmurs correspond 

 with the period of the cardiac cycle in which they oc- 

 cur. A murmur that occurs in the period of auricular 

 systole, is termed presystolic or auricular systolic ; one 

 that occurs in the period of ventricular systole, systolic ; 

 one that occurs during the diastole of the ventricles, 

 diastolic,- and should the murmur immediately follow 

 the first or second sound, post-systolic or post-diastolic 

 respectively. In relation to their seat of generation, 

 cardiac murmurs are designated mitral, aortic, tri- 

 cuspid, and pulmonary. All murmurs should be timed 

 by the carotid pulse, not by their relation to the apex- 

 beat. Murmurs are most frequently caused by some 

 change in one of the cardiac valves or orifices, allowing 

 of a reflux of the blood, or obstructing its onward pro- 

 gress. A table of organic endocardial murmurs is ap- 

 pended. M., Cardio-pulmonary, an abnormal sound 

 produced outside of the heart, but closely resembling 

 one due to organic valve-disease. Such murmurs are 

 of frequent occurrence, and may be due to displace- 

 ment of, or pressure upon, the heart, effusion into the 

 pleural cavity, changes in the pleura of the precordial 

 area, changes in the lung overlying the heart, or changes 

 in the pericardium. M., Cephalic, a murmur heard 

 at different parts of the scalp in anemia ; it is prob- 

 ably venous in origin. M., Diastolic, a murmur oc- 

 curring during the diastole of the heart. M., Direct, 

 a murmur produced by obstruction to the blood-cur- 

 rent as it is passing in its normal direction. M., 

 Duroziez's, the double murmur sometimes heard in 

 the femoral artery in aortic regurgitation. See also 

 Signs and Symptoms, Table of. M., Dynamic, one 

 resulting from tumultuous and irregular action of the 

 heart. M., Endocardial, a murmur produced within
