Resumo: The spine is composed of a set of vertebrae, connected by intervertebral discs. It isarticulated through synovial joints present in the articular processes. Because the orca (Orcinus orca) and the horse (Equus caballus) evolved in different habitats, their vertebral formula differs numerically and morphologically. This study aimed to identify and compare morphological differences and adaptive features of the vertebral column of Orcinus orca and Equus caballus. Data was collected through a literature review on number of vertebrae, vertebral shape and morphofunctional adaptive characters for each subject species and related aquatic mammals. According to the literature, both species must have evolved from a single vertebral column morphological model under differential selective environmental pressures. The number of vertebrae per column segment also differs between O. orca and E. caballus, notably because of cervical vertebrae fusion from Atlas to C3 and C4 to C7. Comparing the vertebral formula of Orcinus orca C7, T11-13, L10-12, Ca20-24 = 50-54, and Equuscaballus C7, T18, L6, S5, Ca15-21 = 51-57, clearly corroborates the single model hypothesis.

Devido a orca (Orcinus orca) e o cavalo (Equus caballus) habitarem ambientes diferentes, a formula vertebral difere numérica e morfologicamente. O objetivo desse trabalho consistiu em identificar diferenças morfológicas e caracterí­sticas adaptativas nas colunas vertebrais de Orcinus orca e Equus caballus. A pesquisa foi realizada através de levantamento bibliográfico, descrevendo caracterí­sticas como a quantidade, formato e caracterí­sticas morfofuncionais adaptativasdas vértebras de cada espécie. Foram consideradas referências bibliográficas que descreviam a evolução de cada espécie e artigos cientí­ficos relacionados à coluna vertebral de mamí­feros aquáticos. Levantou-se que ambas espécies devem ter evoluí­do a partir de um único modelo de coluna vertebral ancestral, através de pressões ambientais seletivas diferenciais. A quantidade numérica de cada segmento que forma a coluna também mostrou diferenças entre O. orcaand E. caballus, sendo que a fusão das cervicais de Atlas a C3 e o fusionamento de C4 a C7 foram as mais notáveis. A fórmula vertebral da Orcinus orca [C7, T11–13, L10–12, Ca20–24 = 50–54] e Equus caballus [C7, T18, L6, S5, Ca15-21 = 51-57] claramente corroboram a hipótese de origem a partir do modelo único.Atas de Saúde Ambiental - ASA (ISSN 2357-7614)2016-12-19info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://revistaseletronicas.fmu.br/index.php/ASA/article/view/1478Atas de Saúde Ambiental - ASA (ISSN 2357-7614); v. 4 n. 1 (2016); 105-1122357-7614reponame:Atas de Saúde Ambientalinstname:Faculdades Metropolitanas Unidas (FMU)instacron:FMUporhttps://revistaseletronicas.fmu.br/index.php/ASA/article/view/1478/1154Copyright (c) 2018 Luiz Carlos Fabio Junior, Missae Dora Uemurainfo:eu-repo/semantics/openAccessFabio Junior, Luiz CarlosUemura, Missae Dora2018-11-08T15:01:32Zoai:ojs.fmu.br:article/1478Revistahttps://revistaseletronicas.fmu.br/index.php/ASA/indexPRIhttps://revistaseletronicas.fmu.br/index.php/ASA/oai||asa.revista@gmail.com2357-76142357-7614opendoar:2018-11-08T15:01:32Atas de Saúde Ambiental - Faculdades Metropolitanas Unidas (FMU)false
