Resumo: | The teleost Poecilia vivipara are characterized as euryhaline, in other words, they modulate gill cell behavior to survive in environments with varying salinity. P.vivipara gills have a set of striated skeletal muscles, abductor and adductor muscles, which plays an important role in the respiration process. This study aimed to describe the morphology of gill muscles during the early stages of development and perform an initial morphological characterization of adults P.vivipara. Moreover, it aimed to analyze the effects of different concentrations of salinity on the morphological characteristics of muscle fibers in fingerlings´ gills. Results showed that the muscle fibers are formed between phases 2 and 3 of embryonic development. At this stage of development, gill muscles are inserted into the basal portion of gill filament, possibly in the bulkhead of cartilage that supports the gills, and organized in muscle bundles located along the gill filament. This morphological organization remains in adults. An increase in the diameter of the fibers and muscle bundles was observed in fingerlings exposed to concentrations of sea salt, which allows relating the body size of P.vivipara with the degree of salinity of the environment where they live.KEYWORDS: guppy; gill muscle; ontogeny; salinity. |

As brânquias do P.vivipara possuem um conjunto de músculos estriados esqueléticos, os músculos adutores e abdutores, que têm papel importante no processo de respiração. O presente trabalho teve como objetivos principais descrever a morfologia das estruturas musculares branquiais durante os estágios iniciais do seu desenvolvimento e realizar uma caracterização morfológica inicial em guarus adultos. Além disso, visou-se analisar os efeitos das diferentes concentrações de salinidade nas características morfológicas das fibras musculares branquiais de alevinos. Como resultados das investigações, observou-se que as fibras musculares são formadas entre a fase 2 e 3 do desenvolvimento embrionário. Nesse estágio de desenvolvimento, os músculos branquiais estão inseridos na porção basal do filamento branquial, possivelmente no tabique de cartilagens que suporta as brânquias, e organizados em feixes musculares localizados ao longo do filamento branquial. Essa organização morfológica permanece nos adultos. Detectou-se um aumento no diâmetro das fibras e dos feixes musculares em alevinos expostos a concentrações de sal marinho, o que permite relacionar o tamanho corporal dos guarus com o grau de salinidade do ambiente onde vivem.PALAVRAS-CHAVE: guaru; músculo branquial; ontogênese; salinidade.Universidade Federal de Goiás2011-09-29info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionResearchAvaliado por paresPesquisa Científicaapplication/force-downloadtext/htmlhttps://revistas.ufg.br/vet/article/view/1027310.5216/cab.v12i3.10273Brazilian Animal Science/ Ciência Animal Brasileira; Vol. 12 No. 3 (2011); 478-486Ciência Animal Brasileira / Brazilian Animal Science; v. 12 n. 3 (2011); 478-4861809-68911518-2797reponame:Ciência animal brasileira (Online)instname:Universidade Federal de Goiás (UFG)instacron:UFGporhttps://revistas.ufg.br/vet/article/view/10273/9677https://revistas.ufg.br/vet/article/view/10273/9678Antunes, Adriana MariaRocha, Thiago LopesMorais, José Oscar RodriguesSabóia-Morais, Simone Maria T.info:eu-repo/semantics/openAccess2012-07-01T14:38:07Zoai:ojs.revistas.ufg.br:article/10273Revistahttps://revistas.ufg.br/vetPUBhttps://revistas.ufg.br/vet/oai||revistacab@gmail.com1809-68911518-2797opendoar:2024-05-21T19:55:44.655139Ciência animal brasileira (Online) - Universidade Federal de Goiás (UFG)true |
