UTERUS — (NORMAL ANATOMY). mencing sometimes at a distance of \\'"—3"' above the margin of the uterine lip and ex- tending upwards either centrally or to one side of the median line, and reaching as far as the internal os, it terminates here in a bulbous expansion, or branches out into numerous small ramifications. From either side of this median perpendicular fold are given oft' lateral plicae, varying in number, but being usually not less than 6—9. These soon bifurcate once or twice, so that the number of folds will vary considerably, according as they are counted immediately at, or at some distance from, their line of junction in the central raphe. The uppermost pair of lateral those next to the raphe, often exhibit the same bulbous extremity; and these together fill the upper or narrowest portion of the cer- vical canal. Lower down, where the canal be- comes wider, the lateral plica? spread out on either side of the central raphe, the upper ones in an oblique, the middle and lower ones in a more horizontal direction. These soon bifurcate, and form a series of oblique, hori- zontal, or arched laminae, whose arrangement varies much according to the fulness of the folds, the depth of the furrows between them, and the distance by which the laminae are se- parated. If the latter are prominent and very closely set, their margins may overlie each other, like the branchial laminae of a fish, so that no intermediate furrows are perceptible; or the folds, not being very prominent, may merely lie in apposition, leaving no visible in- terspace until they are drawn asunder ; but when the plica? are less full and prominent a furrow is perceptible between each. These furrows of necessity take the same direction as the plicae by which they are bounded. In another common form which the plicae assume, the general lines of folds and interme- diate furrows take a more vertical direc
