EARDRUM DISPLACEMENT FOLLOWING STAPEDIUS MUSCLE CONTRACTION by
Simultaneous monitoring in human subjects on the same ear of eardrum displacement by tympanomanometry, and acoustical impedance by the Madsen bridge, provided information concerning contraction of the stapedius muscle and its effect on eardrum displacement. Extensive control procedures were employed to elicit only the stapedius reflex: lower intensity auditory stimulation, electrocutaneous stim...
متن کاملMuscle Changes in Aging
UNLABELLED Muscle physiology in the aging athlete is complex. Sarcopenia, the age-related decrease in lean muscle mass, can alter activity level and affect quality of life. This review addresses the microscopic and macroscopic changes in muscle with age, recognizes contributing factors including nutrition and changes in hormone levels, and identifies potential pharmacologic agents in clinical t...
متن کاملDegenerative Changes in the Mitochondria of Flight Muscle from Aging Blowflies
Mitochondria from flight muscle of aging blowflies, Phormia regina, were examined morphologically and biochemically with the electron microscope. An age-dependent degeneration of the mitochondria that is characterized, in part, by the reorganization of the inner membrane into myelin-like whorls has been found. The concentric rings increase in size and number, eventually replacing the normal cri...
متن کاملAbsence of both stapedius tendon and muscle.
During surgery for otosclerosis, it is common for the surgeon to cut the stapedius tendon. The absence of the stapedius muscle with its tendon is uncommon. In this study, we present a case of the absence of the unilateral stapedius tendon and muscle. During dissections of adult temporal bones, the absence of the stapedius tendon and muscle was found in one case. The tympanic cavity was explored...
متن کاملChanges in the muscle strength and functional performance of healthy women with aging
Background: Lower limbs antigravity muscles weakness and decreased functional ability have significant role in falling. The aim of this study was to find the effects of aging on muscle strength and functional ability, determining the range of decreasing strength and functional ability and relationship between them in healthy women. Methods: Across-section study was performed on 101 healthy wom...
