摘　　要：为了研究人心脏神经元的构筑，观察了人心脏神经节的分布数量和神经连接。光镜下发现大量神经节（５５０±１４９）或神经元分布在人的心房和心室表面。神经节和神经纤维束形成神经节丛。在左右心房表面，心房神经节丛靠神经纤维束彼此相连；在心室顶侧面心室神经节丛也彼此相连。但是在光镜下未发现心房神经节丛和心室神经节丛之间有神经纤维束相连。这个形态学发现支持把心房神经节丛和心室神经节丛区分为两个相对独立的功能单位的概念。In order to study the architectuer of human cardiac neurons, the location and mumber of human cardiac ganglionated plexuses and their nervous connections were investigated. With a dissecting microscope it was found that numerous ganglia (550 ± 149) or neurons were identified on the atrial and ventricular surface of the human hearts (n= 6).The atrial ganglionated plexuses formed by ganglia and nerve fiber bundles were connected with each other by nerve fiber bundles on the right and left atrial surface; the same thing happened on cranial ventricular surface. But the connection between atrial and ventricular ganglionated plexuses was not found with the microscope. This anatomical finding supportes the idea that the atrial plexuses rnay be functionally divided from the ventricular plexuses.
