Abstract

The buffalo ejaculatory ducts are examined by transmission electron micro scopy. They are lined by pseudostratified columnar epithelium.. The lining epithelium is composed of columnar principal cells and basal cells. The basal cells are less differentiated, while the principal columnar cells are observed in different physiological activites. One prircipa! well-type shows absorption and transport activity and is characterized by many small basally located mitochondria. Other principal ceil-type is involved in phago cytosis of spermatozoa and is provided with many phagocytic vacuoles containing digested spermatozoa and condensing phagolysosomes.
