Histology of ductus epididymidis and ductus deferens Male Pangolin (Manis Javanica)

This study aims to describe the histology of the ductus epididymidis, ductus deferens male pangolin (Manis Javanica). This study used ductus epididymidis, ductus deferens from one male pangolin that had been fixed in Bouin solution for 48 hours and transferred to 70% alcohol. For histological observations, tissue samples were taken from each part of the ductus epididymidis, ductus deferens, which is transversely from the cranial, medial and caudal sections and processed lengthwise by standard histology with hematoxylin eosin (HE) and Masson's trichrome (MT) staining. The results of this study indicate that the ductus epididymidis is composed of cylindrical epithelium in a row of cilia surrounded by connective tissue and the lumen contains spermatozoa. Cauda epididymidis has the widest lumen diameter between the head and the corpus epididymidis. The ductus deferens is composed of cylindrical epithelium, many pseudo ciliated rows surrounded by thick connective tissue and a thin layer of smooth muscle with an enlarged end called the ampulla. The ampulla is surrounded by smooth muscle and thick connective tissue, dense connective tissue. Ampulla is composed of serous-type cells with the cell nucleus located in the center.
