Anal sphincter electromyography carried out during dilatation of the anesthetized urethra revealed a reflexogenic zone at the bladder neck, dilatation of which causes contraction of the anal sphincter. This reflex appears to be separate and distinct from previously described reflexes of the bulbocavernosus type which are triggered by somatic sensory stimuli. A possible role of this reflex in the separation of the functions of micturition and defecation is postulated.
在麻醉状态下的尿道扩张过程中进行的肛门括约肌肌电图检查显示，膀胱颈处存在一个反射ogenic区，其扩张会导致肛门括约肌收缩。这种反射似乎与先前描述的由躯体感觉刺激触发的球海绵体肌型反射是分开且不同的。推测了这种反射在排尿和排便功能分离中的可能作用。
