Abstract

The Mongolian gerbil, belonging to the Muridae family, is characterized as an economic asset in the pet market due to its easy management. Current research analyzes and describes the origin of the nerves that make up the lumbosacral plexus in the species, foregrounding comparative anatomy, especially among wild rodents. The experiment, approved by the Committee of Institutional Bioethics, involved 15 animals which had been used in other studies and were donated to the Laboratory of Applied Animal Morphophysiology of the Federal Rural University of the Semi-Arid, Mossoró, Rio Grande do Norte, Brazil. The animals were fixed in a water solution of formaldehyde 10%. After 72 hours, they were dissected, the abdominal cavity was opened and eviscerated, and the psoas minor, psoas major and the quadratus lumborum muscles were removed to inspect the nerves that form the lumbosacral plexus. Results were given in percentages and grouped in tables. The lumbosacral plexus of the Mongolian gerbil frequently derived from the ventral roots of the last thorax nerves, from the seven lumbar nerves and from the four sacral nerves (Type II - T12-S4). The nerves of the gerbil´s lumbosacral plexus are the iliohypogastricus, ilioinguinalis, cutaneus femoris lateralis, genitofemoralis, femoralis, obturatorius, ischiadicus, gluteus cranialis, pudendus, gluteus caudalis and rectales caudales nerves. Information on the origin of the nerves of the gerbil´s lumbosacral plexus and their description is relevant for clinical and surgical studies, and for the application of techniques or anesthetic drugs.
