Macro-anatomic Investigations on the Plexus Lumbosacrales of Japanesse Quail (Coturnix coturnix japonica)

This study was carried out to investigate the origin and distribution of plexus lumbosacrales on the Japanesse quail. Fourty quails were used in this study. Following the anaesthesing of the animals, cavity of the body was opened. Animals were fixed with 10% formaldehyde after draining of their bloods. The nerves constituting plexus lumbosacrales were dissected and were taken photos. It was found out that the plexus lumbosacrales were formed by seven rami ventrales of synsacral spinal nerves in Japanesse quail. It was determined that plexus lumbales had given in n. ilioinguinalis, n. cutaneus femoris, n. femoralis, n. coxalis cranialis, n. saphenus and n. obturatorius, truncus cranialis; n. coxalis caudalis, n. peroneus, truncus medianus; n. tibialis and truncus caudalis had given in rami musculares and n. cutaneus femoris caudalis. It was observed that the last branch of lumbar plexus was connected with the first branch of plexus sacralis also known as n. furcalis. Plexus lumbales were composed of three rami ventrales of synsacral spinal nerves in Japanesse quail. On the other hand, plexus sacrales was made up of four rami ventrales of synsacral spinal nerves in Japanesse quail. Finally, it was determined that there were significant differences in the number, thickness, distribution of the spinal nerves constituting the plexus lumbosacralis, the formation of plexus and in the separation of branches in Japanesse quail.
