- adj. Of, relating to, or consisting of flesh or muscle tissue.
Century Dictionary and Cyclopedia
- Fleshy; sarcodous: especially noting the contractile tissue of muscles: as, sarcous elements, the form-elements of muscular tissue.
- adj. anatomy fleshy; applied to the minute structural elements that make up muscle fibre
GNU Webster's 1913
- adj. (Anat.) Fleshy; -- applied to the minute structural elements, called
sarcous elements, or sarcous disks, of which striated muscular fiber is composed.
- From Ancient Greek flesh. (Wiktionary)
“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.”
“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.”
“This sarcous element really consists of two parts, superimposed one on the top of the other, and when the fiber is stretched these two parts become separated from each other at the line of Hensen (Fig. 376, A).”
“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.”
“When the sarcostyle is stretched to its full extent, not only is the clear portion well-marked, but the dark portionthe sarcous elementis separated into its two constituents along the line of Hensen.”
“Schäfer explains these phenomena in the following way: He considers that each sarcous element is made up of a number of longitudinal channels, which open into the clear part toward the membrane of Krause but are closed at the line of Hensen.”
“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.”
“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.”
“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.”
“On two nothing could be seen but little masses of transparent viscid fluid; but when these were examined under a high power, fat-globules, bits of fibro-elastic tissue, and some few parallelograms of sarcous matter, could be distinguished, but not a vestige of transverse striae.”
