The optical density of acetylcholinesterase was greater in the unbranching bundle than in atrioventricular node and branching bundle, and other stain in different parts of the atrioventricular junction area was the same.

The present results suggest that the parasympathetic fibers in the atrioventricular node and the bundle of His originate from the cholinergic neurons in the interatrial septum.

该结果证实房室结及房室束区副交感神经纤维来源于房间隔内的胆碱能神经元。

The results showed that S100 positive nerve tissues were abundantly distributed in the cardiac conduction system, and the relative density varied in different regions, the rank order being sinoatrial node> atrioventricular node> bundle of His and bundle branches.

结果显示：S100阳性的神经组织在心脏传导系统内广泛分布，其含量以窦房结最多，房室结次之，希氏束和束支最少。

The atrioventricular bundle courses superiorly-anteriorly along the posterior margin ( or crest) of the muscular interventricular septum to the posterior-inferior edge of pars membranacea septi.

房室束沿室间隔肌部的后缘走向上前，至室间隔膜部的后下缘分出左束支。

The distribution of parasympathetic nerves in the unbranching portion of the atrioventricular bundle is denser than that in the other parts of the atrioventricular junction area.

副交感神经在房室束未分叉部的分布较其他部位多。
