腹腔-肠系膜上神经节内腹部内脏器官的代表区

目的 探讨支配腹部内脏器官的交感节后神经元在腹腔－肠系膜上神经节内的代表区。方法 用ＨＲＰ逆行标记法，显微镜描图仪做连续切片描图记录，计数标记细胞的面数密度，并经统计学处理。结果 猫脾、胰、肾、十二指肠和空间肠交感节后神经元在腹腔－肠系膜上神经节内具有各自的集中分布区和分散分布区，亦即各自的局部定位区。支配脾的交感节后神经元集中区位于该节的左侧上部，支配胰的交感节后神经元集中区位于该节两侧的上中后

REPRESENTATIVE REGION OF VISCERAL ORGANS OF ABDOMEN IN THE CELIAC-SUPERIOR MESENTERIC GANGLION

Objective To explore representative region of sympathetic postganglionic neurons innervating visceral organs of abdomen in the celiac|superior mesenteric ganglion. Methods Using retrograde transportable method of HRP,tracing was made with micro|tracing|instrument and the number of labeled cell in the celiac|superior mesenteric ganglion was counted with stereological method and statistically. Results The results indicated that concentrated region and scattered region of sympathetic postganglionic neurons of spleen,panceras,kidney,duodenum,jejunum and ileum were located respectively in celiac|superior mesenteric ganglion.The sympathetic postganglionic neurons of spleen were concentrated in the left upper region of celiac|superior mesenteric ganglion;those of pancreas were concentrated in upper middle posterior region;those of both kidney were concentrated in both side middle inferior region;those of duodenum were concentrated in right posterior upper region;those of jejunum and ileum were concentrated in middle inferior region.The scattered region of sympathetic postganglionic neurons of those organs were located respectively in the periphery of respective concentrative region. Conclusion The present results proved that there were functional representative region of those organs in celiac|superior mesenteric ganglion.
