Resumo: | Epididymal region of domestic adult quail of the italina variety was studied by morphometric analysis concerning to the proximal and distal efferent ductules and the epididymal duct. They formed the proper segmental epididymal region structure in domestic quail prior observed during the four seasons of the year in the Botucatu city/SP/Brazil (22°53'09''S, 48°26'42''W, 840m), with tropical altitude climate, average annual temperature of 20,7 degrees. Parameters such as the tubular diameter and the luminal diameter, structure of the lining epithelium and luminal content, of all tubules of the epididymal region, were analyzed referring each segmental tubular area disposed along the epididymal region. It was verified that the efferent ductules occupied the major proportional distribution inside the epididymal region and plus the epididymal duct presented striking quantitative and qualitative variations during the autumn and spring. These seasons respectively represented the quiescent and active phases of this quail annual testis cycle. During summer and winter some variations of the epididymal region morphology were verified. Morphological data obtained in winter and in summer respectively allow characterizing them as intermediary phases of the annual reproductive cycle. However, no remarkable change in the proximal efferent ducts and distal efferent ducts was observed in winter and summer, for the spring events, such as already described during the annual testicular cycle of domestic quail. So the epididymal region of the domestic quail of the Italian variety is a single organ, whose size varies in the autumn, with minor relative average, and in the other seasons in which this organ maintain its usual dimensions. |

Estes dúctulos que formam a própria estrutura segmentar da região epididimária da codorna doméstica foram observados nas quatro estações do ano, na cidade de Botucatu/SP/Brasil (22°53’09’’S, 48°26’42’’W, 840m), com clima tropical de altitude, média anual de temperatura de 20,7 graus. Parâmetros tais como: o diâmetro tubular e o diâmetro luminal, estrutura do epitélio de revestimento e do conteúdo luminal, de todos os túbulos da região epididimária, foram analisados referindo-se a cada zona segmentar da região epididimária. Verificou-se que os dúctulos eferentes, em conjunto, ocupam a maior área proporcional no contexto da região epididimária e junto com o ducto epididimário apresentam marcantes variações quantitativas e qualitativas, especialmente visíveis durante o outono e a primavera. Estas estaçõesrepresentam, respectivamente, a fase quiescente e a fase proliferativa do ciclo sexual masculino dessa ave. Os dados morfológicos obtidos no inverno e no verão, respectivamente, possibilitaram caracterizá-los como fases intermediárias do ciclo reprodutivo nesta espécie. Contudo, nenhuma variação marcante nos dúctulos eferentes proximais e dúctulos eferentes distais foi verificada no inverno e no verão, relativamente aos eventos de primavera, tal como já fora descrito durante o ciclo testicular anual da codorna doméstica. Então a região epididimária da codorna doméstica da variedade italiana é um único órgão, cujo tamanho varia no outono, com menor média relativa, e nas outras estações o órgão mantém suas dimensões usuais.EDUFU2017-07-25info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://seer.ufu.br/index.php/biosciencejournal/article/view/3431910.14393/BJ-v33n4a2017-34319Bioscience Journal ; Vol. 33 No. 4 (2017): July/Aug.; 1007-1014Bioscience Journal ; v. 33 n. 4 (2017): July/Aug.; 1007-10141981-3163reponame:Bioscience journal (Online)instname:Universidade Federal de Uberlândia (UFU)instacron:UFUenghttps://seer.ufu.br/index.php/biosciencejournal/article/view/34319/20671Copyright (c) 2017 Antônio Marcos Orsi, Karina Simões, Maíra Aparecida Stefanini, Maria José Salete Viottohttps://creativecommons.org/licenses/by/4.0info:eu-repo/semantics/openAccessOrsi, Antônio MarcosSimões, KarinaStefanini, Maíra AparecidaSalete Viotto, Maria José2022-02-14T01:57:03Zoai:ojs.www.seer.ufu.br:article/34319Revistahttps://seer.ufu.br/index.php/biosciencejournalPUBhttps://seer.ufu.br/index.php/biosciencejournal/oaibiosciencej@ufu.br||1981-31631516-3725opendoar:2022-02-14T01:57:03Bioscience journal (Online) - Universidade Federal de Uberlândia (UFU)false |
