Última Histologia da glândula de albúmen de Pomacea canaliculata (Lamarck, 1822) (Mollusca, Gastropoda, Pilidae) Zoologia Mesquita,Eliane de Fátima Marques de; Coelho,Arnaldo Campos dos Santos; Santos,Jefferson Andrade dos. In this paper the authors give a histological analysis of the albumen gland of mature and immature females of Pomacea canaliculata (Lamarck, 1822). In the immaturity, tthe gland doesn't show any secretory activity, although in the maturity this activity is indicated by the presence of a homogeneous and eosinophilic material in its lumen. We could notice in the capsule gland of matures females a calcareous element is present as a granular and basophilic deposit. The albumen gland is envolved by a thin conjunctive layer that can be seen in van Gieson's coloured preparations.

In this paper the authors give an anatomical and histological analysis of the genital duct in mature and immature females of Pomacea canaliculata (Lamarck, 1822). Anatomically, the vagina has an equal dimension in its extension, varying in form and volume, according to the maturation period. In the immaturity, it has a smaller diameter and volume. In the maturity, the vagina increases in volume, having the aspect of a tumescent organ, and in certain specimens shows an albuminous pink thread in its lumen. Histologically, the calcigenic activity of the gland is evidentiated by the presence of an amorphous and basophilic mass, without nuclear material. This material has a fragmented aspect in the vagina lumen that reacts positively in van Kossa's coloured...

In this paper the authors give an anatomical and histological analysis of the male reproductive system of Pomacea canaliculata (Lamarck, 1822). Anatomically, the testis is better evidentiated than the ovary. In the structure of the testis a great number of very small channels converges to a single one. The male copulatory organs result of transformations that take place in the inner surface on the palial membrane. Histologically, the testis of immature males shows seminiferous ducts with round egg-shaped forms. In their lumens we could notice masses of cells that will originate spermatozoids. The penis has a conjunctive muscular sheath that can be seen in van Gieson's coloured preparations.
