"Vascular" Quotes from Famous Books
 ... danger of caisson work is the "bends," or "caisson disease." In the caisson a man works under high air pressure. When he comes out, the pressure on the fluids of the body is reduced, and this sometimes causes the formation of a gas bubble in the vascular system. If this bubble reaches a nerve-center it causes severe pain, similar to neuralgia; if it gets to the brain it causes paralysis. Day after day men will go into the caisson and come out without trouble, ...

... to me as one cause of spurious eruptions, I have already remarked in the former treatise, namely, the transition that the cow makes in the spring from a poor to a nutritious diet, and from the udder's becoming at this time more vascular than usual for the supply of milk. But there is another source of inflammation and pustules which I believe is not uncommon in all the dairy counties in the west of England. A cow intended to be exposed for sale, having ...

... candlestick. It was this attitude which had made it possible for Doctor Bicknell to save him. So terrific had been the sweep of the razor that had he had his head thrown back, as he should have done to have accomplished the act properly, with his neck stretched and the elastic vascular walls distended, he would have of a certainty ...

... is an extremely important means of transition: to give one instance—there are fish with gills or branchiae that breathe the air dissolved in the water, at the same time that they breathe free air in their swim-bladders, this latter organ being divided by highly vascular partitions and having a ductus pneumaticus for the supply of air. To give another instance from the vegetable kingdom: plants climb by three distinct means, by spirally twining, by clasping a support with their sensitive tendrils, and by the emission ...

... The vascular connection of vegetable buds with the leaves in whose bosoms they are formed is confirmed by the following experiment, (Oct. 20, 1781.) On the extremity of a young bud of the Mimosa (sensitive plant) a small drop of acid of vitriol was put by means of a pen, and, after a few seconds, the leaf ...

... acrior. Acuter sense of extension. The sense of extension was spoken of in Sect. XIV. 7. and XXXII. 4. The defect of distention in the arterial system is accompanied with faintness; and its excess with sensations of fulness, or weight, or pressure. This however refers only to the vascular muscles, which are distended by their appropriated fluids; but the longitudinal muscles are also affected by different quantities of extension, and become violently painful by the ...

... the feathers, but the other times for the feathers only. The pen quills are generally taken from the ends of the wings. When plucked the quills are found to be covered with a membranous skin, resulting from a decay of a kind of sheath which had enveloped them; the interior vascular membrane, too, resulting from the decay of the vascular pith, adheres so strongly to the barrel of the quill as to be with difficulty separated, while, at the same time, the barrel itself is opaque, soft, ...

... support of their excitability, would of itself lead us to presume, that here the vis irritabilis is the reigning dynasty. There is here no confluence of nerves into one reservoir, as evidence of the independent existence of sensibility as sensibility;—and therefore no counterpoise of a vascular system, as a distinct exponent of the irritable pole. The whole muscularity of these animals, is the organ of irritability; and the nerves themselves are probably feeders of the motory power. The petty rills of sensibility flow into the full expanse of irritability, and there lose ...

... experience, than the cold bath. This is so true, that the same author constantly directed infirm persons to use such a degree of exercise before emersion, as might produce increased action of the vascular system, with some increase of heat; and thus secure a force of re-action under the shock, which otherwise might not always take place. The popular opinion, that it is safest to go perfectly cool into the water, is founded on erroneous notions, and ...

But in the air-breathing Vertebrata such an arrangement would obviously be of no use. Consequently, the gill-slits in the sides of the neck (see Figs. ...

... lifting the respective ventricular bands with the tip of the laryngoscope. The vocal cords, which appear white, flat, and ribbon-like in the mirror, when viewed directly assume a reddish color, and reveal their true shelf-like formation. In the subglottic area the tissues are vascular, and, in children especially, they are prone to swell when traumatized, a fact which should be always in mind to emphasize the importance of gentleness in bronchoscopy, and furthermore, the necessity of avoiding this region in tracheotomy ...

... defies all a-priori reasoning. The brain in whalebone-whales does not fill the interior of the cranium; so that the capacity of the one is no measure of the solid bulk of the other. Their food is various, having no relation to the teeth or buccal appendages; vascular structures surround the spinal marrow, and extend in the Balaenopterae into the cavity of the cranium, which seem to be without any analogy in other mammals, or, at the least, a very obscure one, and ...
