These are termed the hydatids of Morgagni {appendices vesicidosi). The course pursued by the Fallopian tube has been given in its relations to the ovary on page 1398. Structure.—The Fallopian tube consists of three coats—serous, muscular, and mucous. The external or serous coat (tunica serosa) is peritoneal. Beneath this lies the tunica adventitia, composed of lax connective tissue. The middle or muscular coat (tunica muscularis) consists of an external longit

Structure.—The Fallopian tube consists of three coats—serous, muscular, and mucous. The external or serous coat (tunica serosa) is peritoneal. Beneath this lies the tunica adventitia, composed of lax connective tissue. The middle or muscular coat (tunica muscularis) consists of an external longitudinal layer (stratum longitudinale), and an internal circular layer [stratum circulare) of smooth muscle fibres continuous with those of the uterus; near the uterine end of the tube an inner longitudinal la\'er is found. The internal or muocus coat (tunica mucosa) is continuous with the mucous lining of the uterus and, at the free extremity of the tube, with the peritoneum. It is thrown into branched longitudinal folds or villi (plicae iubariae), which in the outer, larger part of the tube or ampulla (plicae ) are much more extensive than in the narrow canal of the isthmus (plicae isthmicae). The lining epithelium is simple ciliated. This form of epithelium is also found on the inner surface of the fimbriae, while on the outer or serous surfaces of these processes the epi- thelium gradually merges into the endothelium of the Fimbria ucarica. Fig. 1177.—Dissection of uterine appendages, L from behind. (Henle.) Vessels and Nerves.—The cliief artery of the tube is the tubal branch of the uterine artery (ramus tuharius) (Fig. 1185). It also receives branches from the ovarian (Fig. llSo). Some of the tubal veins empty into the uterine veins, some into the ovarian veins. The lymphatics (Fig. 1186) coming from the tube unite with the trunks coming from the uterus and ovary and terminate in the lateral aortic nodes. The nerves come from the same plexuse
