The fallopian tube is developed from the cranial portion of paramesonephric duct. It is narrower at its medial than lateral end. The most lateral part is called fimbrial. The fimbria ovarica attaches the tube to the lateral pole of the ovary and presumed to aid in ovum transport into the tube. From medial to lateral the tube has parts namely interstitial, isthmus, ampulla, infundibulum and fimbria.
The tube is lined by single layered columnar epithelium with 4 types of cells; ciliated, secretory, peg and basal. Ciliated cells are more numerous in infundibulum and ampullary regions, with secretory cells more often seen in isthmus.
The epithelium shows cyclical changes.
