Estudo macroscópico do nervo isquiático do Quati (Nasua nasua) e suas ramificações

Abstract

The coati (Nasua nasua) is a procionid with a flexible snout, small eyes and ears, which have long canines. They are omnivorous animals with diurnal, terrestrial and arboreal habits, which feed mainly on fruits and small invertebrates. This omnivore has been constituted in an important group among the animals submitted to different studies, which is extremely important even for the understanding of its own evolution, adding to the fact that detailed knowledge of its Anatomy can represent an important factor for their preservation and protection. The objective of this research is, is to know the anatomical aspects of the sciatic nerve, its origin and composition, aiming at a better understanding of the innervation of the pelvic limb of this animal. For this work, 3 orthothanged animals were used, from the Scientific Creatory (CECRIMPAS) -UNIFEOB authorized by IBAMA as 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. The sciatic nerve and its branches were dissected, measured and photo documented. After analyzing the pieces studied, we could observe that the largest nerve in the coati's body is the sciatic nerve, as well as in the feline, swine and goat. This one The nerve derives its fibers essentially from the ventral branches of the lumbar nerves and from the sacral nerves that make up the lumbosacral plexus.
