Mechanosensitive pelvic nerve sensory fibres that innervate the urinary bladder or distal colon have low (<5 mm Hg) or high (>30 mm Hg) thresholds for response to distension. Both low (LT) and high (HT) threshold sensory fibres encode the distending pressure well into the noxious range (>40 mm Hg). (Modified from Sengupta and Gebhart.3)
