| Sumario: | The major splancmc nerve is part of the nervous simpathic system and is placed in the posterior mediastine heading for the abdomen to innerve the abdominal visceras, and it's anatomical knowledge is of great importance to surgical procedures on this region. A descriptive anatomical study aimed to study the origin, trajectory and relationship of the major splancnic nerve. 44 nerves from 22 adult bodies, from both sex, from no defined race and maintained in formol at 10% were dissected. Many ways of origins to the splacnic nerve were observed, with only 7 cases being concordant with the researched authors. There were 25 nerves (56%) made from non sequenced origins. From the right nerves, 14 (63,8%) from the 22 cases originated from three or four roots from the simpathic trunk. In 12 (54,5%) left nerves, two or three contributions from the simpathic range were predominant. 22 nerves (16 from the right and 6 from the left) followed the descendant rout on the medial way and 22 nerves (6 from the right and 16 from the left) headed down following the spine side outline with no medial return. 21 nerves were found (6 from the right and 15 from the left) in a lateral location to the thoracic spine, 16 front-lateral nerves (9 from the right and 7 from the left) and 7 right nerves were anterior to the spine. We concluded there's no origin standard to the major splancnic nerve due to its large variety of origins. The major splancnic nerve may be placed in front to the thoracic spine after it's formation. Therefore, it's expected that this study may enlarge knowledge about the major splancmc nerve and reduce the risks caused by its damage in surgical procedures in the posterior mediastine |
