For this purpose, 18 sheep (eight female Hasmer sheep, three male Hasak sheep and seven female Hasak sheep) were assessed. After induction of anesthesia, the body cavities were opened. The sheep were fixed with formaldehyde after draining of the blood. The nerves of the plexus sacralis were dissected separately and photographed. Both in Hasmer and Hasak sheep breeds, the plexus sacralis was a large anastomotic complex of nerves which gave rise to nerves distributed to pelvic cavity and pelvic limb. It was derived from the ventral branches of the six spinal segments. It was observed that this plexus was formed by the ventral rami of four (first to fourth) sacral spinal nerves as well as ventral ramus of the sixth and fifth lumbar nerves. The results of this study are believed to be improved further with the future morphometric studies and to make a contribution to future anatomical and surgical studies in this area.
