| The domestic dove Columba livia (Gmelin, 1789) is a species well adapted to Brazil and the study of its reproductive biology is part of a broad research project on birds. This essay describes the morphological aspects of the cloaca of female Columba livia, describing compartments lengthwise starting from the head such as the coprodeo, urodeo and proctodeo limited by mucosal folds. Each compartment of the cloaca presents its own morphological characteristics which differ one from the other in form, height and position of mucosal projections, kinds of tissues, presence and histological aspects of glands, presence of lymphonodus. The rectum opens into the coprodeo, the ureter opens into the oviduct and the cloacal sac opening into the proctodeo. Histochemical... |

| The study of the female genital system of Columba livia (Gmelin, 1789) is part of the research on the reproductive biology of Brazilian birds. This work describes the morphological aspects of the ovary of Columba livia, as well as the histological differences observed in the ovarian follicles during the ovocyte maturation process. Ten Columba livia females were studied, whose ovaries had been dissected, fixed in Bouin and Helly solutions, and histologically processed for staining (Hematoxylin-Eosin; Gomori's trichromic and Weigert's technique and Gomori's technique for connective tissue fibers). The ovary has an irregular surface, is located in the abdominal cavity, and relates to the cranial portion of the left kidney and caudal extremity of the left... |

| Known as "domestic dove", the Columba livia (Gmelin, 1789) is a columbidae species widely distributed in Brazil, whose reproductive biology has been studied by many researchers. The testes of 12 Columba livia males were collected and prepared for histologic examination under an optical microscope, the results of which were analysed and photographed. The tunica albuginea that covers the testes consists of a thick, not very cellular layer of dense connective tissue. Groups of interstitial cells with typical morphological appearance and surrounded by loose, well vascularized connective tissue are observable within the organ, between the seminiferous tubules. The seminiferous tubules are thick, intensely wound and, when seen in cross section, show Sertoli... |
