The aim of this study was describe the morphology of the tongue from eight animals by light microscopy and scanning electron microscopy, beyond macroscopic studies. The tongues of K. rupestris had 3.15 ± 0.28 cm of length; 1.0 ± 0.20 cm width at the root; 0.38 ± 0.10 cm width at the body; and, 1.10 ± 0.09 cm width at the apex. Thickness measurements were 0.50 ± 0.09 cm at the apex; 0.30 ± 0.10 cm at the body; and, 0.70 ± 0.10 cm at the root. The free apex had 0.50 ± 0.10 cm in length. The dorsal surface of the tongue contained the fungiform and filiform papillae at the apex and body; conical papillae and a pairs of vallate papillae at the root, and foliated papillae dorsolaterally positioned in the root region. The proper lamina of the dorsal surface of the tongue was composed by keratinized stratified squamous epithelium, in which lingual papillae were found; and, ...

The striking feature of the family Procyonidae is the presence of five digits on the paws. These animals are classified as plantigrades and can do hand movements in different directions. It has habits of climbing trees to procreate and fleeing from danger. It has solitary, crepuscular and nocturnal habits. It feeds on fruits, small vertebrates, insects, nectar, eggs and vegetables. For this work were used two euthanized animals, from the Scientific Breeding Center (CECRIMPAS) – UNIFEOB authorized by IBAMA (Process nº 02027.003731/04-76), fixeded in formaldehyde solution 10%. In this work we report the morphology of the muscles of the raccoon, through dissection and photographic documentation. It was noted here that the origin and insertion of the muscles of the shoulder, arm and of the raccon are similar to that found in dogs, coatis...

Os vertebrados vivíparos desenvolvem um sistema complexo de membranas nutricionais que envolvem o feto. A ocorrência das quatro membranas extraembrionárias (âmnio, córion, alantoide e saco vitelino) é um fato tido como comum a maioria das espécies vivíparas. Estas membranas sofrem modificações morfológicas, interagindo entre si e formando complexos funcionais ou mesmo involuindo com o decorrer da gestação. Existem genes expressos nas membranas extraembrionárias, onde genomas maternos e paternos são necessários para o desenvolvimento dos mamíferos, indicando que não são equivalentes sugerindo a existência de genes que mostram sua expressão. A literatura consultada suporta a ideia de que em determinadas fases de desenvolvimento embrionário, existem fusões de membranas extraembrioná...
