COPD and Human Diaphragm Muscle Dimensions

Chest, 1987
To assess the effect of COPD on diaphragm muscle dimensions, we measured diaphragm muscle mass, thickness, area, and lengths in 18 COPD patients at necropsy. We compared these results with data obtained from 22 non-COPD patients matched with regard to age, height, weight, and sex distribution.

Dystrophy and myogenesis inmdx diaphragm muscle

Muscle & Nerve, 1998
In order to determine why the diaphragm is more severely affected by progressive dystrophy than limb muscles in the mdx mouse, we examined how regional variations in diaphragm dystrophy, the measures of disease and repair, proliferation by committed myogenic cells, and the expression of mitogenic basic fibroblast growth factor (bFGF) could contribute ...

Diaphragm Muscle: Structural and Functional Organization

Clinics in Chest Medicine, 1988
The structural and functional organization of the diaphragm muscle is described in terms of the essential units for neuromotor control. These motor units in the diaphragm vary markedly in their metabolic, contractile, and fatigue properties. Thus, the forces generated by the diaphragm during different ventilatory and nonventilatory behaviors will ...

Radiology of the Diaphragm as Two Muscles

Investigative Radiology, 1983
In order to investigate the postulate that the diaphragm consists of two muscles, cineradiographic studies and plain roentgenograms were taken of the diaphragmatic movement in eight dogs. A characteristic pattern of contraction was seen following direct electric stimulation of each of the sections of the diaphragm, namely the costal muscle, mainly ...

Diaphragm: A vital respiratory muscle in mammals

Annals of Anatomy - Anatomischer Anzeiger, 2016
The diaphragm is a respiratory muscle that is primarily responsible for the respiratory function in normal individuals. In mammals, the diaphragm muscle has been studied from the early days of zoology, comparative and experimental anatomy, physiology, medicine, physics, and philosophy.

Diaphragm muscle fatigue resistance during postnatal development

Journal of Applied Physiology, 1991
postnatal development. Both twitch contraction time and half-relaxation time decreased progressively with age. Correspondingly, the force-frequency curve was shifted to the left early in development compared with adults. The ratio of peak twitch force to maximum tetanic force decreased with age. Fatigue resistance of the diaphragm was highest at birth

Length-tension relationship of mammalian diaphragm muscles

Journal of Applied Physiology, 1983
We tested the hypothesis that the length-tension relationship of diaphragm muscle is different from that of other skeletal muscle. Isometric contractile properties of small bundles of diaphragm muscle from rats, cats, rhesus monkeys, dogs, and pigs were measured in vitro at 37 degrees C.

Mechanical properties of diaphragm muscle in dogs

Medical & Biological Engineering, 1975
The mechanical properties of diaphragm muscle in dogs were measured. A portion of the diaphragm was isolated and formed into a pouch which in turn was connected to various hydraulic circuits. We measured pressure response to electrical stimulation for various voltages, frequencies and baseline pressures; and also contraction time.
