The tuhcB uterina {ff,fig. 188) are two ducts, situated in the substance of the upper margin of the broad hgament. They are "^S-188. also called the tubae Faliopianffijt the Fal- lopian tubes, after Fallopius, who first gave a good descrip- tion of them; they ex- tend from the upper angle of the uterus to the sides of the cavity of the true pelvis. Situation and Di- rection.—Floating, as it were, in the cavity of the pelvis, between the ovaries behind, and tlie round ligaments {g g) in front, they pass transversely out- ward, and at the point where they terminate, bend backward and inward, in order to approach the outer end of the ovary, to which they are attached by a small ligament. Each Fallopian tube is straight in the inner half of its course, but describes certain wind- ings in the remaining outer portion, which are so considerable in certain cases, and especially when the tube has been the seat of chronic inflammation or of dropsy, as to i-esemble in some degree the windings of the vas deferens. Moreover, accidental adhe- sions of the expanded extremity very frequently give it an entirely different direction from the one it usually takes. The tubes may be drawn down with tire ovaries into a hernial sac, as I have several times observed. The length of the Fallopian tube is four or five inches, but it sometimes varies on the two sides. The canal in their interior is very narrow along their inner half, but gradu- ally enlarges as it proceeds outward to their termination, which is expanded and divided into
