Reproductive Biology of Bothrops erythromelas from the Brazilian Caatinga

Figure 7

Light micrographs of the ductus deferens and ampulla ductus deferentis in Bothrops erythromelas. (a) Ampulla ductus deferentis showing the presence of folds and crypts in the epithelium. (b) Distal ductus deferens presenting low and pseudostratified epithelium. (c) Ampulla ductus deferentis stained with bromophenol blue. (d) Distal ductus deferens stained with bromophenol blue. (e) Reaction to PAS in the ampulla ductus deferentis. (f) Reaction to PAS in the distal ductus deferens. Asterisks indicate the sperm mass; bm = basement membrane; ct = connective tissue; Ep = epithelium; Ep(c) = pseudostratified epithelium with formation of crypts; M = muscularis; BB+ = positive reaction to bromophenol blue; PAS+ = positive reaction to periodic-acid-Schiff.
