Abstract
In the present study, female genitalia of 15 apparently healthy non- pregnant goat aged from 12-36 months and immediately slaughtered goat were utilized, and then the stage of the estrous cycle is determined by the presence of mature ovarian follicles or corpus luteum on the ovarian surface. The uterine tubes are removed gently and the tissue samples were collected from the following regions of the uterine tube, infundibulum with fimbriae, ampulla, and isthmus and UTJ.
The specimen for light microscopy were immediately fixed in 10% NBF and processed for paraffin technique. Sections of 5µm thickness were obtained. They underwent H&E stain, silver impregnation technique, Masson’s trichrome stain, AB (PH 2.5) and PAS technique. Also, some minute specimens (1 mm3) for transmission electron microscopy were fixed in a buffered GA/FA fixative. Then processed till ultrathin sections were cut and stained with uranyl acetate and lead citrate.
The anatomical studies revealed that the goat uterine tube was a simple tortuous tube that consisted of four regions; infundibulum with fimbriae, ampulla, isthmus, and UTJ.
The histological study revealed that the wall of infundibulum with fimbriae consisted of tunica mucosa- submucosa and tunica serosa. The wall of the ampulla, isthmus and UTJ consisted of tunica mucosa, tunica sub mucosa, tunica muscularis and tunica serosa.
The tunica mucosa of goat uterine tube was characterized by the presence of folds that was long and highly branched forming primary, secondary and tertiary folds in both infundibulum with fimbriae and ampulla but it decreased in number and branching toward isthmus until it became few, short and less- branched.
