Answer

Answer

When the PMC is deactivated, the urge to urinate disappears, allowing the patient to delay urination until finding a socially acceptable time and place. When urination is appropriate, the brain removes its suppression of the PMC via the periaqueductal gray matter, allowing the urinary sphincter to open and the detrusor to contract and empty the bladder.
