机械或热刺激的各种皮肤区域产生反射的变化，在膀胱麻醉猫。当膀胱静止时，皮肤的机械或热刺激仅在会阴区受到刺激时导致膀胱张力的反射性增加。这种皮-膀胱兴奋性反射是一种脊髓反射，其传出弧位于盆神经。当膀胱以1-3分钟的频率出现自发的、大的、有节奏的排尿收缩时，这些收缩通常被会阴、腹部或胸部皮肤的机械或热刺激抑制，按有效性的顺序。有时，抑制之后是随后的兴奋。这种反射抑制大排尿收缩的传出弧也在盆神经中。无论是兴奋性还是抑制性膀胱皮肤反射，伤害性刺激都比非伤害性刺激更有效。
Mechanical or thermal stimulation of various skin areas produced reflex changes in the urinary bladder in anesthetized cats. When the bladder was quiescent, mechanical or thermal stimulation of the skin resulted in a reflex increase in the tonus of the bladder only when the perineal area was stimulated. This cutaneo-vesical excitatory reflex was a spinal reflex with its efferent arc in the pelvic nerves. When there were spontaneous, large, rhythmic micturition contractions of the bladder at a frequency of 1-3 min these contractions were usually inhibited by mechanical or thermal stimulation of the skin of the perineum, abdomen or chest in this order of effectiveness. Sometimes, the inhibition was followed by a subsequent excitation. The efferent arc for this reflex inhibition of the large micturition contractions was also in the pelvic nerves. For both the excitatory and the inhibitory cutaneo-vesical reflex responses, noxious stimulation was much more effective than non-noxious stimulation.
