FIGURE 2 in Comparative morphology of the seminal receptacles of Ocypode quadrata (Fabricius, 1787) (Brachyura, Ocypodoidea)

FIGURE 2. Microscopic view of the seminal receptacles of Ocypode quadrata. A: Detail of the mesodermic wall showing the secretor epithelium, muscular layer and the conjunctive tissue. Scale bar: 50 µm. B: Detail of a fold in the mesodermic epithelium. Scale bar: 50 µm. C: General view of the meso-ectodermic transition with the presence a high folds. Scale bar: 100 µm. D: Detail of the ectodermic fold showing the stratified epithelium, the muscular layer and the cuticular layer Scale bar: 50 µm. CL: cuticular layer, CT: conjunctive tissue, EC: ectodermic fold, EST: ectodermic stratified epithelium, MF: mesodermic fold, ML: muscular layer, MSE: mesodermic secretor epithelium, SPZ: spermatozoa. The zone of the meso-ectodermic epithelium transition in indicated by an arrow. Stained with HE.
