LIGHT MICROSCOPICAL STRUCTURE OF THE EFFERENT DUCTULES AND EPIDIDYMIS IN THE TUFTED CAPUCHIN MONKEYS, Cebus apella

the light microscopical structure of the efferent ductuli and epididymis were examined in the tufted capuchin monkeys. the efferent ductules are lined by a simple cuboidal epithelium, with two cell types: ciliated and non-ciliated cells. the epididymal duct is lined by a pseudostratified epithelium with stereocilia, that is made up of four cell types: principal, basal, apical and migratory cells (intraepithelial lymphocytes). although there are some clear differences, the histological appearance of the excurrent ducts and of the component epithelia of the epididymis, is remarkably similar to that reported for the others mammals
