This pedunculated vesicle represents theremains of the duct of the pronephros, and is common to both sexes ;low columnar or cuboidai epithelium forms the lining of its dilatedsac and stalk as far as pervious. THE OVIDUCT. The oviduct, or Fallopian tube, consists of three coats,—aninner mucous, a middle muscular, and an outer serous. The mucous membrane of the oviduct is thrown into longitu-dinal folds, which correspond in their amplitude to the generalvariation in the size of the tube, being low towards the small uterineend and increasing in height and in complexity on approaching theexpanded fimbriated extremity of the canal. On transverse sectionthrough the smaller portions of the tube, the longitudinal folds giveto the lumen a generally stellate outline, the complexity of the figure 231 additionmucous.

The membrane of the . r Fig. 272. oviduct consists of a nbro-elastic tunicapropria and a singlelayer of columnarciliated epithelialcells, whose ciliarywave sweeps fromthe fimbria towardsthe uterine end ofthe tube. All partsof the canal are linedwith ciliated cells, in-cluding the inner sur-face of its expandedovarian end; at thefree edge of the lat-ter the ciliated co-lumnar cells of thetubal surface are re-placed by the flatendothelial plates of the peritoneum which invests the outer aspectof the tube. The outer layers of the tubal mucous membrane contain scatteredlongitudinal bundles of involuntary muscle, which represent apoorly-developed muscularis mucosae ; outside these a thin layer offibrous connective tissue answers to a submucosa
