Valsalva,

Antonio M., Italian anatomist, 1666-1723.
aneurysm of sinus of Valsalva - a congenital thin-walled tubular out-pouching usually in the right or noncoronary sinus with an entirely intracardiac course.
teniae of Valsalva - the three bands in which the longitudinal muscular fibers of the large intestine, except the rectum, are collected. Synonym(s): teniae coli
Valsalva antrum - a cavity in the petrous portion of the temporal bone. Synonym(s): mastoid antrum
Valsalva ligaments - the three ligaments that attach the auricle to the side of the head. Synonym(s): auricular ligaments
Valsalva maneuver - any forced expiratory effort against a closed airway.
Valsalva muscle - a band of vertical muscular fibers on the outer surface of the tragus of the ear. Synonym(s): tragicus muscle
Valsalva sinus - the space between the superior aspect of each cusp of the aortic valve and the dilated portion of the wall of the ascending aorta. Synonym(s): aortic sinus
Valsalva test - when the heart is monitored during the Valsalva maneuver, there is a characteristic complex sequence of cardiocirculatory events, departure from which indicates disease or malfunction.
