The innervation to the cardiac organs and vessels of the octopods Eledone cirrhosa, E. moschata and Octopus vulgaris is described from vitally stained fresh material and wax-embedded sections. This innervation arises from the paired visceral nerves and includes two main peripheral ganglia (fusiform and cardiac) on each side. Several new details of the innervation are reported. Nerves supplying the lateral venae cavae arise from the ventricular nerves at the level of the ventricle. Nerve fibres run to the efferent branchial vessels from the cardiac ganglia. A small ganglion, lying on the auriculo-ventricular nerve, is described for some specimens of both species of Eledone, and is named the auricular ganglion. Commissural strands linking the right and left ventricular nerves of either side are found in Eledone, comparable to those previously described from Octopus. The detailed branching pattern of the innervation shows considerable individual variation and consistent interspecific differences. In E. cirrhosa the fine fibres innervating the inner and outer muscle layers of the auricle show distinct differences in their configuration. Innervation at the surface of the ventricular lumen and around the coronary arterial vessels shows evidence of specialization. The muscle of the branchial heart, particularly the valve leaflets at the junction of the heart and the lateral vena cava, is abundantly innervated. The observations are discussed in relation to other cephalopods and to their probable physiological significance. It is suggested that they provide evidence for a greater degree of neural influence in the control of the cardiac organs than is usually supposed and that they support the idea that the lateral venae cavae have a significant role in the generation of circulatory pressures.
通过对活体染色的新鲜材料和石蜡包埋切片的观察，描述了卷毛艾氏章鱼（Eledone cirrhosa）、麝香艾氏章鱼（E. moschata）和普通章鱼（Octopus vulgaris）心脏器官和血管的神经支配情况。这种神经支配起源于成对的内脏神经，每侧包括两个主要的外周神经节（梭形和心脏形）。报告了神经支配的几个新细节。供应侧腔静脉的神经起源于心室水平的心室神经。神经纤维从心脏神经节延伸至鳃出血管。在两种艾氏章鱼的一些标本中，描述了位于房室神经上的一个小神经节，并将其命名为耳神经节。在艾氏章鱼中发现了连接两侧左右心室神经的连合束，类似于先前在章鱼中描述的那些连合束。神经支配的详细分支模式显示出相当大的个体差异和种间一致的差异。在卷毛艾氏章鱼中，支配心耳内、外肌层的细纤维在形态上表现出明显差异。心室腔表面和冠状动脉血管周围的神经支配显示出特化的迹象。鳃心的肌肉，特别是心脏与侧腔静脉交界处的瓣膜小叶，有丰富的神经支配。结合其他头足类动物及其可能的生理意义对这些观察结果进行了讨论。有人认为，这些观察结果为神经在心脏器官控制中发挥比通常认为的更大程度的影响提供了证据，并且支持侧腔静脉在循环压力产生中具有重要作用的观点。
