Somatic modulation of spinal reflex bladder activity mediated by nociceptive bladder afferent nerve fibers in cats.
The goal of the present study was to determine if supraspinal pathways are necessary for inhibition of bladder reflex activity induced by activation of somatic afferents in the pudendal or tibial nerve. Cats anesthetized with α-chloralose were studied after acute spinal cord transection at the thoracic T9/T10 level. Dilute (0.25%) acetic acid was used to irritate the bladder, activate nocicepti...
متن کاملInvolvement of Methysergide-sensitive 5-ht Receptor in Pudendal Nerve Inhibition of Nociceptive and Non-nociceptive Bladder Activity in Cats
Hypothesis / aims of study Understanding the neurotransmitter mechanisms involved in pudendal nerve inhibition of bladder activity could lead to identify new pharmacological targets for overactive bladder. Currently little is known about the effect of 5-hydroxytryptamine (5-HT) 2 receptor on micturition reflex. This study used methysergide, a non-specific 5-HT2 receptor antagonist, and naloxone...
متن کاملSympathetic β-adrenergic mechanism in pudendal inhibition of nociceptive and non-nociceptive reflex bladder activity.
This study investigated the role of the hypogastric nerve and β-adrenergic mechanisms in the inhibition of nociceptive and non-nociceptive reflex bladder activity induced by pudendal nerve stimulation (PNS). In α-chloralose-anesthetized cats, non-nociceptive reflex bladder activity was induced by slowly infusing saline into the bladder, whereas nociceptive reflex bladder activity was induced by...
متن کاملInfluences of neck afferents on sympathetic and respiratory nerve activity.
It is well established that the vestibular system influences the sympathetic nervous system and the respiratory system; presumably, vestibulosympathetic and vestibulorespiratory responses participate in maintaining stable blood pressure and blood oxygenation during movement and changes in posture. Many brainstem neurons that generate vestibulospinal reflexes integrate signals from the labyrinth...
متن کاملMyocardial ischemia recruits mechanically insensitive cardiac sympathetic afferents in cats.
Chest pain caused by myocardial ischemia is mediated by cardiac sympathetic afferents. Although silent nociceptors exist in somatic structures and some visceral organs, their presence in the heart remains uncertain. The present study examined the presence and the functional characteristics of mechanically insensitive cardiac sympathetic afferents using an electrical search technique. Single-uni...
