【摘要】 为了研究犬心房和心室表面神经节丛的分布。方法：用尼氏染色法光镜下观察犬心脏表面主要神经节丛。结果：在犬心房表面的右房侧壁、左房背侧、房间隔区脂肪垫内和心室表面位于主动脉和肺动脉之间、主动脉右侧、左冠状动脉根部周围脂肪垫内有许多神经节和神经纤维交织成的神经节丛。心房与心室表面各神经节丛内神经节和神经元分布不均衡，ＲＡＧＰ、ＤＡＧＰ和Ａ－ＰＧＰ内神经节和神经元较多。在犬心脏各部位脂肪垫内和心肌间隙等处均见有大量神经纤维，聚集成束或丛，有的与神经节相连。结论：犬心脏表面神经节和神经元分布不均衡。更多还原

【Abstract】 Objective:To investigate the distribution of canine superficial cardiac neurons. Methods:The canine main cardiac superficial ganglia plexus were observed by means of Nissl staning and optical microscope. Results: There were many ganglia and nerve fibers forming ganglionated plexuses in the fat pats of right atrium, dorsal atria, interatrial,orgins of aorta and pulmonary artery as well as origins of right and left coronary arteries. The distribution of ganglia and neurons in each ganglionated plexuses was not proportionated. More ganglia and neurons were found in RAGP,DAGP,A-PGP than in other ganglia plexus. Numerous nerve fibers were detected in various fat pads of atria and ventricles as well as intelmyocardlocytes. These nerve fibers converged into bundle or jungle, some of them connected with ganglia. Conclusion:The distribution of ganglia and neurons in each ganglionated plexuses was not proportionated.更多还原
