Sarcomeric Oscillations in Frog Skeletal Muscle Fibers

Science, 1968
Brief asynchronous, small-amplitude, cyclic, longitudinal displacements of the striations of frog skeletal muscle fibers were observed with ordinary light microscopy after application of caffeine and certain quaternary ammonium compounds. With time these oscillations became synchronized and evolved into peristaltic-like movements. The oscillations were

Myosin types in human skeletal muscle fibers

Histochemistry, 1980
By combining enzyme histochemistry for fiber typing with immunohistochemistry for slow and fast myosin a correlation between fiber type and myosin type was sought in human skeletal muscle. Fiber typing was done by staining for myofibrillar ATPases after preincubation at discriminating pH values.

Dynamic shape of tapered skeletal muscle fibers

Journal of Morphology, 1991
AbstractThe muscle fibers of the feline biceps femoris have tapered ends, across which tension is transmitted to the endomysium. The angle of taper of 11 ends, measured on scanning electron micrographs, varied between 0.16° and 1.18°. The muscle fibers are highly variable in cross‐sectional shape.

Skeletal Musculature. Red Muscle Fiber

1985
Red muscle fibers have a smaller diameter, fewer myofibrils (1), and thus more sarcoplasm and myoglobin than the white fibers. The form and structure of the nuclei and Golgi apparatus are identical in both types of fiber. The major difference is the considerably greater number of crista-rich mitochondria (2) in the red fibers.

The Adaptive Potential of Skeletal Muscle Fibers

Canadian Journal of Applied Physiology, 2002
Mammalian skeletal muscle fibers display a great adaptive potential. This potential results from the ability of muscle fibers to adjust their molecular, functional, and metabolic properties in response to altered functional demands, such as changes in neuromuscular activity or mechanical loading.

Effects of myotoxins on skeletal muscle fibers

Progress in Neurobiology, 1995
This review highlights various aspects of a number of experimental myological alterations, induced by different chemical toxicants, including anticholinesterase, colchicine, vincristine, chloroquine, tetanus toxin, botulinum toxin, reserpine and emetine.

Along- and cross-muscle fiber shear moduli in skeletal muscle

Journal of Biomechanics
AbstractThe material properties of muscle play a central role in how muscle resists joint motion, transmits forces internally, and repairs itself. While many studies have evaluated muscle’s tensile material properties, few have investigated muscle’s shear properties.

Regeneration of Skeletal Muscle Fibers after Necrosis

1990
I am going to review the normal process of regeneration after necrosis in skeletal muscle and compare it with what happens in Duchenne dystrophy. Dr. Karpati and I have devised an experimental method for producing a focal lethal injury of skeletal muscle qells in which the sequence of steps can be closely followed. We call it experimental micropuncture
