-
In muscle there is the same thing, viz., a framework of spongioplasm staining with hematoxylinthe substance of the sarcous elementand this encloses a clear hyaloplasm, the clear substance of the sarcomere, which resists staining with this reagent.

-
Gradually, new sarcomeres (contractile units) are laid down to share the work load and reduce the wall stress.
-
The sarcous element does not lie free in the sarcomere, for when the sarcostyle is stretched, so as to render the clear portion visible, very fine lines, which are probably septa, may be seen running through it from the sarcous element to the membrane of Krause.

-
Line scans were determined for portions of myofibrils that were straight, contained five or more sarcomeres, and had striations relatively perpendicular to the long axis of the myofibril.
-
The actin filaments found in the sarcomeres of striated muscles, as well as in stress fibers and microvilli in nonmuscle cells, are stable, unbranched structures.
-
When the muscular fiber is contracted the clear part of the muscular substance is driven into these channels or tubes, and is therefore hidden from sight, but at the same time it swells up the sarcous element and widens and shortens the sarcomere.
IV. Myology. 2. Development of the Muscles
-
The sarcomere is situated between two membranes of Krause and consists of (1) a central dark part, which forms a portion of the dark band of the whole fiber, and is named a sarcous element.

-
In muscle there is the same thing, viz., a framework of spongioplasm staining with hematoxylinthe substance of the sarcous elementand this encloses a clear hyaloplasm, the clear substance of the sarcomere, which resists staining with this reagent.
IV. Myology. 2. Development of the Muscles
-
When, on the other hand, the fiber is extended, this clear substance is driven out of the tubes and collects between the sarcous element and the membrane of Krause, and gives the appearance of the light part between these two structures; by this means it elongates and narrows the sarcomere.
IV. Myology. 2. Development of the Muscles
-
In this way the contraction is brought about: under stimulation the protoplasmic material (the clear substance of the sarcomere) recedes into the sarcous element, causing the sarcomere to widen out and shorten.

-
The sarcomere of PSE pork was shorter than that of normal pork because of the partial denaturation of PSE myosin.
-
The difference in the spacings in the top epicardium layer and the rest of the heart may indicate that sarcomere lengths in those regions are different.
-
A sarcostyle may be said to be made up of successive portions, each of which is termed a sarcomere.

-
Factors contributing to the additional improvement include increases in oxygenation, right ventricular function, cardiac output, number of sarcomeres, and muscle mass, and a decrease in glucocorticoid use.
-
Electron microscopy was used to examine ultrastructural evidence of injury, including sarcomeric disruption, disorganisation of myofilaments, misalignment of adjacent sarcomeres, and distortion or absence of Z-lines.
-
At the same time, however, it has been reported that the zeta line is constructed to position a thick filament at the trigonal point of the three thin filaments in the opposite sarcomere.
-
The R193H cTnI mutant alone encroaches on this limit as it has a dominant effect in all combinations to cause a Ca An equally important factor that likely impacts the additive effects of two activating mutant alleles is the combined incorporation of each mutant into the sarcomere given the central role thin filament stoichiometry and cooperativity plays in the regulation of contraction
