Striated muscles in visceral organs of vertebrates
Pathologists involved in the examination of small rodent tissues are familiar with the presence of striated muscle in walls of intrapulmonary veins. Because these striated muscles express cardiomyocyte markers and are involved in rhythmical contraction during systole, this morphologic arrangement was named “pulmonary myocardium”. Striated cardiac muscles of intrapulmonary veins have also been f...
متن کاملModeling Mechanical Patterns for Striated Muscles
Muscles show a surprisingly large variety of functions when they mechanically respond to different environmental requests. However, the in vivo workloop studies distinguish well only four patterns of skeletal muscles, producing positive, negative, almost zero and zero net works, that qualifies them respectively as motors, brakes, struts, and springs. While much effort of comparative biologists ...
متن کاملVariations of the Contractile Apparatus in Smooth and Striated Muscles
Structural information is presented for three muscle systems-mammalian smooth muscle at rest and partially active, living toad striated muscle at rest and contracting, and glycerinated rabbit psoas muscle under various conditions of pH and ionic environment. In the smooth muscle no evidence of organized myosin filaments has been found. In the striated muscle the myosin-to-actin distance can var...
متن کاملExpression of various sarcomeric tropomyosin isoforms in equine striated muscles
In order to better understand the training and athletic activity of horses, we must have complete understanding of the isoform diversity of various myofibrillar protein genes like tropomyosin. Tropomyosin (TPM), a coiled-coil dimeric protein, is a component of thin filament in striated muscles. In mammals, four TPM genes (TPM1, TPM2, TPM3, and TPM4) generate a multitude of TPM isoforms via alte...
متن کاملthe Pathogenesis of Waxy Degeneration of Striated Muscles (zenker's Degeneration)
In view of theoretical deductions and the positive results obtained in the above experiments, it would seem probable that the production of waxy degeneration depends upon the action of lactic acid which is formed by the living muscle under the stimulation of infecting bacteria or their toxins, the formation of large amounts of lactic acid and its accumulation being perhaps favored by defective ...
