The same woman who would die in twenty-three years from ovarian cancer.
In the ovarian FIG.
The two long ovarian sacs communicate with each other by a transverse bridge before uniting to form the terminal canal.
Into each ovarian sac behind the transverse junction opens a slender tube, which is greatly coiled, and, in its turn, opens into a spherical "spermathecal sac."
The sole difference is therefore that in Eudrilus the ovarian sac gives rise to a tube which bifurcates, one branch meeting a corresponding branch of the other ovary of the pair, while the second branch reaches the exterior.
In the former, the duct, leading from the ovarian sac, and swelling along its course into the spherical sac, the "spermatheca," is highly suggestive of the oviduct and receptaculum of the Eudrilidae.
This is clearly the same process in essence as that of the formation of a vitellogenous gland from part of the primitive ovary, or of the feeding of an ovarian egg by the absorption of neighbouring potential eggs; but here the period at which the sacrifice of one egg to another takes place is somewhat late.
This by successive divisions forms a group of four to eight cells, which subsequently pass through the blastoderm, and dividing into two groups become symmetrically arranged and surrounded by the rudiments of the ovarian tubes.
G, Germ-cells surrounded by rudiment-cells of ovarian tubes.
On the inner surface of both valves several well-defined muscular, vascular and ovarian impressions are observable; they form either indentations of greater or less size and depth, or occur as variously shaped projections.
Should this take place into a closed gland space it will give rise to cysts, which may attain a great size, as is seen in the ovarian adenomata.
To James Matthews Duncan (1826-1890) we chiefly owe a saner and broader comprehension of the relative importance of the local and the general conditions which enter into the causation of uterine and ovarian disorders.
In operations for diseases of the pelvis, ovarian dropsy, cancer of the uterus, and other grave diseases of the region, success has been stupendous.
The solitary ovule springs erect from the base of the ovarian cavity.
In the female, each ovary consists of a large number of ovarian tubes, in which swollen chambers containing the egg-cells alternate with smaller chambers enclosing nutrient material.
Deep to these is the ovarian stroma, composed of fibrous tissue, and embedded in it are numerous nests of epithelial cells, the Graafian follicles, in various stages of development.
That end of each which lies in front of the ovary is called the fimbriated extremity, and has a number of fringes (fimbriae) hanging from it; one of the largest of these is the ovarian fimbria and is attached to the upper or tubal pole of the ovary.
Into distinct ovarian and vitellarian regions.
In McDowell Park there is a monument to the memory of Dr Ephraim McDowell (1771-1830), who after 1795 lived in Danville, and is famous for having performed in 1809 the first entirely successful operation for the removal of an ovarian tumour.
In the Graptoloidea certain lateral and vesicular appendages of the polypary in the Lasiograptidae have been looked upon as connected with the reproductive system; and in the umbrella-shaped synrhabdosomes already referred to, the common centre is surrounded by a ring of what have been regarded as ovarian capsules.
The ovaries always contain spermatozoa, some of which project through the ovarian wall into the body cavity.
The ovule is usually contained in an ovary, and all plants in which the ovule is so enclosed are termed angiospermous; but in Coniferae and Cycadaceae it has no proper ovarian covering, and is called naked, these orders being denominated gymnospermous.
