In the toad, Bufo vulgaris, the pulmocutaneous artery, which is innervated by a fine branch of the laryngeal nerve, was shown to be a reflexogenic area affecting the systemic blood pressure. Distension of the vascularly isolated pulmocutaneous artery evoked falls in systemic blood pressure. Impulses in bursts, synchronous with the systolic rise of the blood pressure, were recorded from the peripheral cut end of the laryngeal nerve when all branches, save the one innervating the pulmocutaneous artery, had been divided. Differing from mammalian baroreceptors, those in toads occurred with a marked latency in response to rises in blood pressure. A hyperbolic relation was obtained between the pressure and the latency. Existence of these baroreceptors in pulmocutaneous artery was confirmed in preparations in vitro. Punctate stimulation was used to localize the baroreceptive site.
在蟾蜍（Bufo vulgaris）中，肺皮动脉由喉神经的一个细支支配，已被证明是一个影响全身血压的反射ogenic区域。血管分离的肺皮动脉扩张会导致全身血压下降。当除了支配肺皮动脉的那一支以外的所有分支都被切断后，从喉神经的外周切断端记录到了与血压收缩期上升同步的脉冲群。与哺乳动物的压力感受器不同，蟾蜍的压力感受器在血压升高时出现明显的潜伏期。压力与潜伏期之间呈双曲线关系。在体外制备物中证实了肺皮动脉中存在这些压力感受器。采用点状刺激来定位压力感受位点。
