Figure 3 in Macro- and microscopic morphology of the reproductive system of Leptinaria unilamellata (d'Orbigny, 1835) (Mollusca: Pulmonata: Subulinidae)

Figure 3. (A) Ovotestis of Leptinaria unilamellata formed by groups of follicular acini; nearby is situated a large network of blood vessels (asterisk). (B) The male germinative lineage (arrow head) is centrally arranged and the female germinative lineage (arrow) is in the outer part of the same follicle. (C) Hermaphrodite duct (hd) with a central nucleus and numerous long cilia. (D) Follicular cells (arrow head) are capable of producing cytoplasmic expansions that enclose the oocytes in vitellogenesis (arrow). Haematoxylin-eosin stained. Scale bar = 50 µm.
