Abstract:
There is a great deal of discrepancy among the descriptions of the formation ofsplanchnic nerves. Our present descriptions of the splanchnic nerves are based on thefindings of dissection on 70 cadavers, and the details are as follows: 1. The greater splanchnic nerves varied in origin from the fourth to the elevenththoracic sympathetic ganglion, while the lesser and the lowest both varied in origin fromthe eighth thoracic sympathetic ganglion to the first lumber sympathetic ganglion. According to the upper limit of origin, the greater splanchnic nerve may be dividedinto 3 types: Type 1. High origin: T4-5 occurred on 42 sides (30%). Type 2. Intermediate origin: T6-7 appeared on 86 sides (61.44%). Type 3. Low origin: T8-9 was present on 12 sides (8.5%). It must be pointed out that besides the sympathetic ganglia, some splanchnic nervesmay take origin from the intersegmental rami. 2. In our specimens, the frequency of occurrence of the lowest splanchnic nervewas 77.85%. 3. The number of roots which took part in the formation of the splanchnic nerveswere not equal. This unequality was due to the combination of some roots into commontrunks. According to our present research, the roots of the greater splanchnic nervevaried in number from one to seven (the most common number being 3), the lesser fromone to five (the most common number being 1) and the lowest from one to three (themost common number being 1). 4. The splanchnic nerves usually pierced the diaphragm separately. The space be-tween the medial crus and the intermedial crus of the diaphragm was the most commonplace of piercing. In this article, the splanchnic ganglia were also fully described.
