Corpuscle   Listen
noun
Corpuscle  n.  
1.
A minute particle; an atom; a molecule.
2.
(Anat.) A protoplasmic animal cell; esp., such as float free, like blood, lymph, and pus corpuscles; or such as are imbedded in an intercellular matrix, like connective tissue and cartilage corpuscles. See Blood. "Virchow showed that the corpuscles of bone are homologous with those of connective tissue."
3.
(Physics) An electron. (archaic)
Red blood corpuscles (Physiol.), in man, yellowish, biconcave, circular discs varying from 1/3500 to 1/3200 of an inch in diameter and about 1/12400 of an inch thick. They are composed of a colorless stroma filled in with semifluid haemoglobin and other matters. In most mammals the red corpuscles are circular, but in the camels, birds, reptiles, and the lower vertebrates generally, they are oval, and sometimes more or less spherical in form. In Amphioxus, and most invertebrates, the blood corpuscles are all white or colorless.
White blood corpuscles (Physiol.), rounded, slightly flattened, nucleated cells, mainly protoplasmic in composition, and possessed of contractile power. In man, the average size is about 1/2500 of an inch, and they are present in blood in much smaller numbers than the red corpuscles.

"Corpuscle" Quotes from Famous Books



... to him there was no one else could fill it so well. Claudius had the felicity to be married four times, and left several sons, but Fate had it that he should be followed by Nero, his stepson, who called himself "Caesar," yet in whose veins there leaped not a single Caesarean corpuscle. ...

... of its development, a white blood corpuscle is seen to modify by division; but in fully-developed blood such division is never seen. It is probable that colourless white corpuscles are given to the adult blood by the lymphatic glands. Every irritation of ...

... is called the aorta. Soon after it leaves the heart the aorta begins to send out branches to various organs. These divide in the tissues again and again until they become so small that only one corpuscle can pass through at a time, as shown in the ...

... observable, is varied. It may cause the corpuscles to run too closely together, and to adhere in rolls; it may modify their outline, making the clear-defined, smooth, outer edge irregular or crenate, or even starlike; it may change the round corpuscle into the oval form, or, in very extreme cases, it may produce what I may call a truncated form of corpuscles, in which the change is so great that if we did not trace it through all its stages, we should be puzzled to know whether the object looked at were indeed a blood-cell. All ...

... has been introduced into the blood and trace its development there. At first it is slender and rod-like in shape. It has some power of movement in the blood-plasm. Very soon it attacks one of the red blood-corpuscles and gradually pierces its way through the wall and into the corpuscle substance (Fig. 99); here it becomes more amoeboid and continues to move about, feeding all the time on the corpuscle substance, gradually destroying the whole cell. As the parasite feeds and grows there is deposited within ...

... (caryobasis) is formed of the enveloping membrane and a mesh-work of nuclear threads running across the interior, which is filled with the nuclear sap. In a knot of the network is contained the dark, stiff, opaque nuclear corpuscle or nucleolus. When the impregnation of the ovum sets in, the greater part of the germinal vesicle is dissolved in the cell; the nuclear membrane and mesh-work disappear; the nuclear sap is distributed in the protoplasm; a small portion of the nuclear ...

... required, or two of nitrogen where only one was wanted,—and the face of the world might have been vastly different. Not only did much depend on their coming together, but upon the order of their coming; they must unite in just such an order. Insinuate an atom or corpuscle of hydrogen or carbon at the wrong point in the ranks, and the trick is a failure. Is there any chance that they will hit upon a combination of things and forces that will make a machine—a watch, a gun, or even a ...
— The Breath of Life • John Burroughs

... into the domain of PATHOLOGICAL ANATOMY, we find the same elements in morbid growths that we have met with in normal structures. The pus-corpuscle and the white blood-corpuscle can only be distinguished by tracing them to their origin. A frequent form of so-called malignant disease proves to be only a collection of altered epithelium-cells. Even cancer itself has no specific anatomical element, and the diagnosis of a cancerous tumor by the ...

... for a certain diagnosis. Other signs must be used as a check on the blood examination for the establishment of the existence of anaemia. For instance, many cases here recorded had full normal or even supra-normal corpuscle-count, with a good percentage of haemoglobin. Yet they presented every external sign of poverty of blood: pallor of skin and, more important still, of mucous membranes, cold extremities, anorexia, indigestion, ...
