"Medullary" Quotes from Famous Books
 ... rate and increased respiratory efforts. In cardiac failure, as the systolic pressure falls the diastolic is likely to be increased, and the pressure pulse thus diminishing, allows insufficient blood to go to the medullary centers, and death soon occurs. Therefore, in acute illnesses a sustained pressure pulse gives a better prognosis than a diminishing pressure pulse. The strenuous measures that should he used to lower a high diastolic pressure are contraindicated ...

... represent a portion of the fibrous region of Calamodendron wood, may give an idea of the shrinkage that has taken place therein. In Figs. 11 and 12, which show a few tracheae and medullary rays of the ligneous bands of the same plant, we observe the same phenomenon. We might cite a large number of analogous examples, but shall be content to give the following: Figs. 13 and 15 represent radial ...

... cease, when animals are immersed in airs which possess no oxygen. It may also subsequently answer another important purpose, as it probably affords the material for the production of the sensorial power; which is supposed to be secreted in the brain or medullary part of the nerves; and that the perpetual demand of this fluid in respiration is occasioned by the sensorial power, which is supposed to be produced from it, being too subtle to be long confined in any part of ...

... outer portion, like the bark of a tree, consisting of a dense sheath of flattened scales, then comes an inner lining of closely-packed fibrous cells, and frequently an inner well-marked central bundle of larger and rounder cells, forming a medullary axis. The transverse section (Fig. 7) shows this exceedingly well. The end of a hair is generally pointed, sometimes filamentous. The lower extremity is larger than the shaft, and terminates in a conical bulb, or mass of cells, which forms the root of the hair. ...

... Yes, my dear; it is obtained from a plant which grows in the East Indies: the medullary, or pithy part of which, is beaten with water, and made into cakes. These the Indians use as bread. This, when reduced into granules and dried, forms the sago we find so nourishing to persons of weakly and delicate constitutions. ...

... be seen that the shaft is a hollow cylinder, formed of compact tissue, enclosing a cavity called the medullary canal, which is filled with a pulpy, yellow fat called marrow. The marrow is richly supplied with blood-vessels, which enter the cavity through small openings in the compact tissue. In fact, all over the surface of bone are minute canals leading ...

... of the scales varies in different breeds of wool. The (p. 003) outer scales enclose inner medullary cells, which often contain pigment matter. A transversed section of the wool fibre shows the presence of a large number of cells. Sometimes wool fibres are occasionally met with which have a peculiar white horny appearance; these do not felt or dye ...

... fibrous character and white, is named med'ul-la-ry, (marrow-like.) In every part of the nervous system both substances are united, with the exception of the nervous fibres and filaments, which are solely composed of the medullary matter enclosed in a ...

... Saint-Girons, have brought to light a hearth covered over with a layer of stalagmite; numerous fragments of human bones, crania, femora, tibiae, humeri, and radii were found in this layer, and in that of the subjacent clay. In many cases the medullary orifice had been enlarged to make it easier to get out the marrow. It is impossible to attribute this to a rodent, for the bones gnawed by animals of that kind present a regular series of marks. The conclusion is inevitable: these bones, alike ...

... view in the other life in forms not elsewhere seen; for many things which in man take the form of ideas are there presented as objects of sight. The external memory there presents the appearance of a callus, the internal the appearance of a medullary substance like that in the human brain; and from this what they are can be known. With those that have devoted themselves in the life of the body to the cultivation of the memory alone, and have not cultivated ...

... amber-tree of the ancient world ('Pinites succifer') abounded in resin to a degree far surpassing that manifested by any extant coniferous tree; for not only were large masses of amber deposited in and upon the bark, but also in the wood itself, following the course of the medullary rays, which, together with ligneous cells, are still discernible under the microscope, and peripherally between the rings, being some times both ...
