"Vascular" Quotes from Famous Books
 ... which penetrated the head and were distributed in pairs to the various members of the body, and which were vaguely thought of as carriers of water, air, excretory fluids, etc. Yet back of this vagueness, as must not be overlooked, there was an all-essential recognition of the heart as the central vascular organ. The heart is called the beginning of all the members. Its vessels, we are told, "lead to all the members; whether the doctor lays his finger on the forehead, on the back of the head, on the hands, on the place of the stomach (?), on the arms, or on the feet, ...

... presence, vivacity of manner, general bodily soundness; also defects of many kinds, such as those of the nervous system, of the speech, eyes, ears, skin, also baldness, defects of the muscular system, blood, thyroid glands, vascular system, respiratory system, digestive system, reproductive organs; also defects and peculiarities of the skeleton, etc. This does not mean that all shortcomings are inherited. It does mean, however, that the type of organism is inheritable which lacks resistance to ...

... explicitly, "Two membranes enclose the brain; that about the skull is the stronger; the inner membrane is slighter than the outer one." And further, it should be noted that he describes the latter membrane as a vascular one. The fact of the brain substance being insensible to mechanical irritation was known to Aristotle, and may have been learnt from the practice of Hippocrates. Lastly, it should be remembered that—though this may have been but a lucky guess on Aristotle's part—the relative weight of ...

... instance, in the case of inhibition in the region of the nerves supplying the superior cervical ganglion with nerve force, we will find, first, throughout the area of distribution of the branches of this ganglion a relaxation of the vascular walls. This will be marked by two indications, first, the skin will become flushed and moist; second salivary secretion and lachrymal secretion will be increased. Second, the vagus is now allowed full sway, and we will find slowing ...

... absorbed through the walls of the alimentary canal to the living and active parts of the body. This is one of the functions of the series of structures— heart and blood-vessels, called the circulation, circulatory system, or vascular system. It is not the only function. The blood also carries the oxygen from the lungs to the various parts where work is done and kataboly occurs, and it carries away the katastases to the points where ...

... physiological and the social organisms. But this is not the place for a controversy involving so many technicalities, and I content myself with one remark, namely, that the whole course of modern physiological discovery tends to show, with more and more clearness, that the vascular system, or apparatus for distributing commodities in the animal organism, is eminently under the control of the cerebro-spinal nervous centres—a fact which, unless I am again mistaken, is contrary ...

... on the results of their trip to the College. The arteries, as was anticipated, were found to have undergone calcareous degeneration. There was an hepatic connection through the band, and also some interlacing diaphragmatic fibers therein. There was slight vascular intercommunication of the livers and independence of the two peritoneal cavities and the intestines. The band itself was chiefly a coalescence of the xyphoid cartilages, surrounded by areolar ...

... composed almost entirely of blood-vessels, and is developed upon the inner wall of the uterus, at the point at which the ovum attaches itself after fecundation. The growing fetus is connected with this vascular organ by means of a sort of cable, called the umbilical cord. The cord is almost entirely composed of blood-vessels which convey the blood of the fetus to the placenta and return it again. The fetal blood ...

... that the other systems of organs are developed in the same way, from tubes formed out of simple layers, did not escape Wolff. The nerveless system, muscular system, and vascular (blood-vessel) system, with all the organs appertaining thereto, are, like the alimentary system, developed out of simple leaf-shaped structures. Hence, Wolff came to the view by 1768 which Pander developed in the Theory of Germinal Layers fifty years afterwards. His principles are not literally ...

... the other. I have seen them in the wallaby frequently two inches in length, and with pouches so large, that you could with ease thrust your hand into them; the uteri with their appendages enlarged and apparently very vascular, as well as thickened; but in no one instance at the Abrolhos could I detect a gravid uterus; but I have seen the young adhering to the nipples less than half an inch in length, and in a perfectly helpless state. It is generally supposed that the uterus in the adult animal is not supplied with ...

... the two plants involved. (Jones, 1903; Massey, 1925). That the wilting observed under walnuts is due to a toxic product from the bark of the walnut, and does not result from a lack of water, is substantiated by the fact that the vascular or water conducting system is discolored for several inches above the point of contact with the walnut root. This symptom is very similar to that produced by vascular disease fungi. No such discoloration results from ...

... 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 ...

... uterus in women and of the alimentary canal in both sexes, the state of contraction, of orgasm, of turgescence in the fleshy envelopes, in the muscular layers which protect and inclose the abdomen, the thorax, the principal vascular trunks, and the bony surfaces, must essentially contribute to weaken, to deaden, to nullify, the effect of the blows. Is it not by means of an analogous state of orgasm, which an over-excited will produces, that boxers and athletes find themselves in a condition to brave, ...

... one not unfamiliar with the instrument and the mysteries it reveals, we can assure them that these figures are of supreme excellence. The hazy semitransparency of the embryonic tissues, the halos, the granules, the globules, the cell-walls, the delicate membranous expansions, the vascular webs, are expressed with purity, softness, freedom, and a conscientiousness which reminds us of Donne's microscopic daguerreotypes, while in many points the views are literally truer to nature,—just as a ...

Smith[27]: These structures form an elastic wall to the sensitive foot, and attachment to the vascular laminae; they also admit of increase in width occurring at the posterior part of the foot without destroying the union of the two set of leaves. Further, by their connection with the vascular system of the foot, their elastic movements materially assist the ...

The former, in the Dog, becomes long and spindle-shaped, while in Man it remains spherical; the latter, in the Dog, attains an extremely large size, and the vascular processes which are developed from it and eventually give rise to the formation of the placenta (taking root, as it were, in the parental organism, so as to draw nourishment therefrom, as the root of a tree extracts it from the soil) are arranged ...

... the question whether the water of dewdrops on plants or stones came from the air or the earth, and described a number of experiments to show that under the conditions of observation in Scotland, it was the earth from which the moisture was probably obtained, either by the operation of the vascular system of plants in the formation of exuded dewdrops, or by evaporation and subsequent condensation in the lowest layer of the atmosphere. Some controversy was excited by the publication of Aitken's views, and it is interesting to revert to it because it illustrates a proposition which ...
