title: Gender, bladder distension and hypogastric nerve activity in the cat.
abstract: In the pentobarbitone anaesthetised cat, postganglionic activity was recorded from the whole hypogastric nerve and from hypogastric filaments destined for the bladder wall during bladder distension. A gender difference was observed in whole hypogastric nerve recordings, cardiac-related activity obscuring other components in females with intact internal reproductive organs. In contrast, nerve activity in the vesical hypogastric filaments was dominated by bladder distension-related activity in both sexes. These observations suggest that bladder distension-related activity, which has a continence promoting action on the bladder detrusor muscle, is destined for the bladder wall, while the cardiac-related activity is largely destined for the uterine and vaginal vasculature.
