Abstract: Eight adult donkeys of both sexes, used in applied anatomy classes, constituted the material of the study. The greater splanchnic nerve (N. splanchnicus major) was determined to ramify from the truncus sympathicus from the space between the 13th thoracic sympathetic ganglion and the 17-18th thoracic interganglionic connection on the right side and the space between the 12-13th thoracic interganglionic connection and the 16-17th thoracic interganglionic connection on the left side. The lesser splanchnic nerve (N. splanchnicus minor) was determined to be formed by fibres originating from the 14-15th thoracic interganglionic connection and the 17-18th thoracic interganglionic connection on the right side and the 13-14th thoracic interganglionic connection, the 15-16th thoracic interganglionic connection and the 17th thoracic sympathetic ganglion on the left side. The lesser splanchnic nerve (N. splanchnicus minor) was determined not to exist on the right side in one of the materials examined. The lowest splanchnic nerve (N. splanchnicus imus) was demonstrated to exist on the right side in 4 (50%) and on the left side in 3 (37.5%) of the 8 materials examined. The thoracic splanchnic nerves were determined to give off branches to the suprarenal gland (glandula suprarenalis), behind the diaphragm and to extend to the celiac ganglion (ganglion celiaca). No marked difference was observed between the right and left sides.
