The structural basis for myogenic and neurogenic control of motility of human Fallopian tubes was studied. In the ampulla distinct muscle layers were absent, and bundles of cells oriented in different axes were in contact with one another by means of randomly located simple apposition contacts; no nexuses were present. The organization was consistent with a spread of electrical activity in either direction throughout all muscle bundles. Nerves were not found in close proximity to muscle and were mostly peripheral, surrounded by connective tissue sheaths and by Schwann cells within the sheath. They could play little role in control of ampullar motility. In the isthmus muscle bundles were grouped into innermost longitudinal layer, circular layer, and outermost layer of mixed orientation. Cell-to-cell connections were mainly by simple apposition contacts; no nexuses were found. There were such connections between cells of bundles oriented in different axes. The organization of muscles suggested that electrical activity could spread in either direction and throughout all layers. Nerves like those in the ampulla were located peripherally, and smaller bundles without connective tissue sheaths were in circular muscle. Few close contacts between nerve and muscle were observed.
对人类输卵管运动的肌源性和神经源性控制的结构基础进行了研究。在壶腹部，没有明显的肌肉层，不同轴向上的细胞束通过随机分布的简单并置接触相互接触；不存在缝隙连接。这种组织结构与电活动在所有肌肉束中双向传播是一致的。未发现神经紧邻肌肉，神经大多位于外周，被结缔组织鞘和鞘内的施万细胞包围。它们在控制壶腹部运动中作用不大。在峡部，肌肉束被分为最内层的纵行层、环形层和最外层的混合方向层。细胞间连接主要通过简单并置接触；未发现缝隙连接。不同轴向上的束状细胞之间存在这样的连接。肌肉的组织结构表明电活动可以在两个方向上并在所有层中传播。与壶腹部类似的神经位于外周，环形肌中有较小的无结缔组织鞘的束状结构。观察到神经与肌肉之间很少有紧密接触。
