"Ovum" Quotes from Famous Books
... the female is sometimes caused by a morbid adhesion of the tube to a portion of the ovary. By what power the mouth of the tube is directed toward a particular portion of an ovary, from which the ovum is about to be discharged, remains entirely unknown, as does also the precise nature of the ... — Searchlights on Health - The Science of Eugenics • B. G. Jefferis and J. L. Nichols
... fully developed at the rate of one in each second, this number would be exhausted in about one month; but since a number of spermatozoa appears to be necessary to produce perfect fertilization, it is quite easy to understand that the number of gemmules introduced into the ovum may be so great that the influence of the male parent may be very marked, even after having been, as regards particular character, apparently dormant for many years." The germinal vesicle of a mammalian ovum being about 1/1000 of ... — Was Man Created? • Henry A. Mott
... alcohol reaching his brain from a drunken mother. Such traits are congenital, but acquired. Native traits date back to the original constitution of the child, which was fully determined at the time when his individual life began, nine months before birth. The "fertilized ovum", formed by the combination of two cells, one from each of the parents, though microscopic in size and a simple sphere in shape, somehow contains the determiners for all the native or inherited traits ... — Psychology - A Study Of Mental Life • Robert S. Woodworth
... far as that of size.[24] The female cell is always much larger than the male; where the former is swollen with the reserve food, the spermatozoa may be less than a millionth of its volume. In the human species an ovum is about 3000 times as large as spermatozoa.[25] The male cellule, differentiated to enable it to reach the female, impregnates and becomes fused within her cellule, which, unlike hers, preserves its individuality and continues as the ... — The Truth About Woman • C. Gasquoine Hartley
... if that hazy contradiction in terms, "personal identity," be once allowed to retreat behind the threshold of the womb, it has eluded us once for all. What is true of one hour before birth is true of two, and so on till we get back to the impregnate ovum, which may fairly claim to have been personally identical with the man of eighty into which it ultimately developed, in spite of the fact that there is no particle of same matter nor sense of continuity between them, ... — Selections from Previous Works - and Remarks on Romanes' Mental Evolution in Animals • Samuel Butler
... usefully employed in producing animal variations could also be used in producing and fixing plant varieties. The pollen or germ of an outstanding good male individual, when brought into contact with the pistil or ovum of an outstanding female individual of the same species will produce a scion that is more likely than any other to have good qualities. Here was the secret of most of the progress which has been made in both animal and plant ... — Northern Nut Growers Association Report of the Proceedings at the Thirty-Seventh Annual Report • Various
... says that the drinking of impure water will cause dropsy of the uterus. Adams, commenting on this, has in mind hydatids, but it is evident that both Hippocrates and his translator and critic have mistaken hydatidiform disease of the ovum for hydatid disease of the womb. In the books which are considered genuine the references to diseases of women are meagre, and it is likely that the author had little special knowledge of the subject. That part of the Hippocratic collection ... — Outlines of Greek and Roman Medicine • James Sands Elliott
... and break up. The ova appear first as small cells in the external substance of the ovary (as at 1), and move inward (2 and 3), surrounded by a number of sister cells, which afford them nourishment. At (4) an ovum with its surrounding group of cells is more distinct and near the centre of the ovary; a fluid is appearing within the ovisac as the development proceeds. (5) is a much more mature ovisac or ... — Text Book of Biology, Part 1: Vertebrata • H. G. Wells
... than by these cases; while, in spite of their exceptional nature, they must be of great interest physiologically, as showing the wide limits of possible variation which thus may even involve the sex, "for an ovule to develop pollen within its interior," says Mr. Salter, "is equivalent to an ovum in an animal being converted into a capsule of spermatozoa. It is a conversion of germ into sperm, the most complete violation of individuality and unity of sex. * * * * The occurrence of an antheroid ovule and a normal ovule on the same carpellary leaf ... — Vegetable Teratology - An Account of the Principal Deviations from the Usual Construction of Plants • Maxwell T.
