Two; one for each Wolffian body. Describe their development. They begin as a layer of germinative epithelium which dips down into the structure of the outer surface of the Wolffian body. These depressions eventually become covered over, thus forming two tubes or canals. What organs are derived from Midler's ducts ? The oviducts, uterus, and vagina. Describe their formation.
