Abstract - The lumbosacral plexus that supplies to the hind limb has been extensively studied in mammals and birds. There is no report on lumbosacral plexus characterization in domestic turkey (Meleagris gallopavo), so far. Here, we investigated the nerve roots in domestic turkey, which accumulate to form the lumbosacral plexus and characterize the branches originating from the plexus. The lumbosacral plexus consists of lumbar and sacral plexuses. Three turkeys were dissected for character- ization of the plexuses. It was found that lumbar plexus was formed by the union of four ventral roots of the spinal nerves, including the last three lumbar and first sacral spinal nerves. Among four roots, the diameter of the third (last lumbar) root was highest, whereas the least was observed in the last root. We observed four branches of the lumbar plexus, including the obturator, cutaneous femoral, saphenus, and femoral nerve. The five roots of spinal nerves, which contributed to form three trunks, formed the sacral plexus of turkey. The three trunks united medial to the acetabular foramen and formed a compact, cylindrical bundle, the ischiatic nerve. The principal branches of the sacral plexus were the tibial and fibular nerves that together formed the ischiatic nerve. Other branches were the caudal femoral cutaneous nerve and the muscular branches. This study was the first work on the lumbosacral plexus of domestic turkey, and these results may serve as a platform for future research.
