Smooth muscle electrical activity was recorded with suction electrodes from the partly or completely uncoiled epididymal duct of the rat in vitro. The electrical activity of the cauda epididymidis consisted of one or few spikes followed by a plateau of 1-2 sec. The frequency of electrical activity declined from the thicker-walled initial segment of the thin-walled initial segment, was increased to the level seen in the initial segment in the thicker, major portion of the caput epididymidis, declined in the corpus and fell steeply in the cauda epididymidis towards the vas deferens. Electrical activity spread over long distances in the distal cauda and epididymal vas. Elsewhere in the epididymis activity remained synchronous only for a short period in short segments.
用吸力电极在体外记录大鼠部分或完全展开的附睾管平滑肌电活动。附睾尾部的电活动由一个或几个尖峰组成，随后是1 - 2秒的平台期。电活动频率从较厚壁的起始段向薄壁的起始段下降，在附睾头较厚的主要部分增加到起始段的水平，在附睾体下降，并在附睾尾部向输精管急剧下降。电活动在附睾尾部远端和附睾血管中远距离传播。在附睾的其他部位，短节段内的活动仅在短时间内保持同步。
