Fig. 5. Transverse section of the pregnant tube
A. Mesoaalpinx. B. B. “Cell Sheet " C. Lumen of Tube diatended,nnd containing a mu: of fibrin. D. D. Gestation uc.
Fig. 5 represents a transverse section of the pregnant tube about 1 mm. nearer the uterus.
The gestation sac is now large, and is seen to be surrounding the circular muscle coat in a very remarkable way.
It is evident that the ovum has split the longitudinal coat from the circular coat and is lying between them.
The wall of the ac is composed of fibrinised muscle tissue deeply infiltrated with trophoblast cells.
Within the cavity lie many villi, covered by-the usual double layer of epithelium. At a few spots this can be seen to -be continuous with the layers of trophoblast cells, which constitute the “cell-sheet.”
No villi are found amongst the maternal tisues.
