Building a myofibril from its component proteins requires the interactions of many different proteins in a process whose details are not understood. Several models have been proposed to provide a framework for understanding the increasing data on new myofibrillar proteins and their localizations during muscle development.

Skeletal muscle cells, more commonly called muscle fibres, are multinucleated syncytia formed during development by fusion of mononucleated precursor cells, the myoblasts. They measure 10–100 μm in diameter and can have lengths from a few millimeters up to almost a meter.

Binding of filamin isoforms to myofibrils
Journal of Muscle Research & Cell Motility, 2000Two filamin isoforms were purified from bovine tissues and characterized. Muscle filamin and nonmuscle filamin had different SDS gel mobilities, proteolytic digestion patterns, myofibrillar binding distributions and myofibril binding affinities. The muscle specific filamin had an apparent molecular weight of 265 kDa and bound primarily to the Z-lines ...

Das Muskelfäserchen (Muskelfibrille, Myofibrille, Myofibril)
1957Ganz wie die Muskelfaser hat auch die Muskelfibrille eine doppelte Gliederung, eine axiale und eine transversale. Die transversale oder quere Gliederung (parallel mit der Querachse) wird dargestellt durch die verschiedenen von der Lichtmikroskopie her bekannten Bander und Zonen, die fur die Querstreifung aller quergestreiften Muskulatur verantwortlich ...

Force depression in single myofibrils
Journal of Applied Physiology, 2010Force depression after active shortening has been observed in different muscle preparations. It has been assumed that force depression is caused by the development of sarcomere length nonuniformities after shortening. However, this hypothesis has never been investigated in a preparation where individual sarcomere lengths could be directly measured ...

Elongation of cross-striated myofibrils
Biochimica et Biophysica Acta, 1956Abstract When myofibrils isolated from the indirect flight muscles of Calliphora were treated under the microscope with freshly-prepared crude suspensions of sarcosomes from the same muscles they elongated by about 4% and then contracted when treatment ceased; several cycles of elongation and contraction could be brought about. Evidence is given that

Gelation of Turkey Breast and Thigh Myofibrils: Changes During Isolation of Myofibrils
Journal of Food Science, 1993ABSTRACT The relationship between functional properties of meat and myofibrils was examined for turkey breast and thigh by determining gel‐forming ability of proteins at each step in a myofibril isolation procedure. Physical properties of thermally induced gels (70°C for 30 min) were determined by torsional fracture analysis.

In nearly every field of science deeper understanding of nature led to investigations into ever smaller features of the object, from macroscopic to microscopic to molecular to atomic to nuclear. At each step change of size we have made a quantum jump in our knowledge about the object.

The fine structure of myofibrils
Experimental Cell Research, 1950Abstract Shadowed electron micrographs show that myofibrils of rabbit striated muscle consist of bundles of long filaments overlaid and perhaps interpenetrated by a structureless material whose distribution determines the banded character of the muscle. The filaments have about the diameter of those of fibrous actin. The photographs show many details

Volume changes in isolated myofibrils
Biochimica et Biophysica Acta (BBA) - Specialized Section on Biophysical Subjects, 1964Volume changes in glycerol-extracted myofibrils were studied. The effect of pH, ion content and ATP concentration on the change in volume was determined. A volume change greater than that attributed to ATP dephosphorylation was observed. The magnitude of the volume change of the entire system was 10−3 cm3 whereas that due to dephosphorylation was 10−6 ...
