The histological sections of oviducts of group C showed three layers: serosa, myosalpinx, endosalpinx the external serosal layer were flat with centrally located nuclei.
The fallopian tubes of the control group A showed normal histological features, a well defined tubal wall consisted of three layers: the internal mucous membrane, the middle muscular layer (myosalpinx) and the external serosa.
The histological sections of oviducts of group B showed three layers: serosa (external layer), myosalpinx (intermediate layer) and endosalpinx (inner layer).
The normal fallopian tubal epithelium is composed of 3 basic epithelial cell types: ciliated cells, secretory cells, and intercalated peg cells, overlying a loose connective tissue submucosa and an outer myosalpinx
, composed of inner circular and outer longitudinal layers.
