Cytological Studies of Fiber Types in Skeletal Muscle
A comparative investigation of the mammalian diaphragm has revealed a correlation between certain cytological aspects of red and white muscle fibers and functional activity. This skeletal muscle presents the advantage of a similar and constant function among the mammals, but its functional activity varies in a quantitative manner. Both the rate of breathing (and hence the rate of contraction of...
متن کاملDiversity and Plasticity of Fiber Types in Mammalian Skeletal Muscle
with different structural and functional properties. The fiber-type profile of different muscles is initially established during development independently of neural influences, but nerve activity has a major role in the maintenance and modulation of fiber-type properties in adult muscle. The molecular mechanisms of activity-dependent muscle fiber plasticity have been the object of intensive inv...
متن کاملPolymorphism of myosin among skeletal muscle fiber types
An immunocytochemical approach was used to localize myosin with respect to individual fibers in rat skeletal muscle. Transverse cryostat sections of rat diaphragm, a fast-twitch muscle, were exposed to fluorescein-labeled immunoglobulin against purified chicken pectoralis myosin. Fluorescence microscopy revealed a differential response among fiber types, identified on the basis of mitochondrial...
متن کاملDistribution of myosin isoenzymes among skeletal muscle fiber types
Using an immunocytochemical approach, we have demonstrated a preferential distribution of myosin isoenzymes with respect to the pattern of fiber types in skeletal muscles of the rat. In an earlier study, we had shown that fluorescein-labeled antibody against "white" myosin from the chicken pectoralis stained all the white, intermediate and about half the red fibers of the rat diaphragm, a fast-...
متن کاملSkeletal muscle: energy metabolism, fiber types, fatigue and adaptability.
Skeletal muscles cope with a large range of activities, from being able to support the body weight during long periods of upright standing to perform explosive movements in response to an unexpected threat. This requires systems for energy metabolism that can provide energy during long periods of moderately increased energy consumption as well as being able to rapidly increasing the rate of ene...
