Viscerosomatic reflexes: a review.

The Role of Pelvic and Perineal Muscles in Reproductive and Excretory Functions

Excretory and reproductive functions are underlaid by autonomicand somatic-neural control that regulates the pelvic and the perineal structures in mammals. Viscera and striated and smooth muscles are involved in complex and multiple reflexes occurring in the pelvic cavity (Komisaruk and Sansone, 2003; Pacheco et al., 1989; Thor and de Groat, 2010). In women, this region must accommodate the gro...

Effects of rectal distensions on nociceptive flexion reflexes in humans.

We previously showed that gastric distension inhibits the somatic nociceptive flexion RIII reflex. To explore further the viscerosomatic interactions, we tested in the present study the effects of rectal distensions on RIII reflexes. Rapid and slow-ramp rectal distensions were performed in 10 healthy volunteers with an electronic barostat. The RIII reflex was continuously recorded from the lowe...

Effects of 17 -Estradiol on Responses of Viscerosomatic Convergent Thalamic Neurons in the Ovariectomized Female Rat

Reed WR, Chadha HK, Hubscher CH. Effects of 17 -estradiol on responses of viscerosomatic convergent thalamic neurons in the ovariectomized female rat. J Neurophysiol 102: 1062–1074, 2009. First published June 24, 2009; doi:10.1152/jn.00165.2009. Ovarian hormones have been shown to exert multiple effects on CNS function and viscerosomatic convergent activity. Ovariectomized (OVX) female rats wer...

Management Strategies for Abdominal Bloating and Distension.

Bloating and distension are among the most common gastrointestinal complaints reported by patients with functional gut disorders and by the general population. These 2 complaints are also among the most prevalent of the severe symptoms reported by patients with irritable bowel syndrome. Nonetheless, only a limited number of published studies have specifically addressed bloating; it is infrequen...
