Análise macroscópica das papilas da língua do Quati

Abstract

The coati (Nasua nasua) is an animal that belongs to the Phylum Chordata, the Mammalia Class, the Carnivorous Order and the Procyonidae Family. These animals have habits of climbing trees to breed, escape from danger and stay overnight and feed on fruits, small vertebrates, insects, nectar, eggs and vegetables. For this work, 3 orthothanized animals were used, from the Scientific Creatory (CECRIMPAS) - UNIFEOB authorized by IBAMA with the Process: nº 02027.003731 / 04-76. The techniques used were latex injection into the abdominal aorta to replenish the arterial bed, followed by fixation in a 10% formaldehyde solution. In this work, the morphology of the coati (Nasua nasua) tongue papillae was described using a macroscopic method of dissection and photographic documentation. The tongues were removed, dissected and divided into three portions: rostral, medium and caudal. Macroscopically, it can be seen that the dorsal surface of the tongue presents filiform, fungiform, ditch and conical papillae distributed in the rostral, middle and caudal regions. According to the results it can be concluded that the coati tongue has macroscopic characteristics similar to canids, varying the number of ditched papillae.
