What triggers the bladder to empty?

As your bladder fills, nerve signals sent to your brain eventually trigger the need to urinate. When you urinate, these nerve signals coordinate the relaxation of the pelvic floor muscles and the muscles of the urethra (urinary sphincter muscles). The muscles of the bladder tighten (contract), pushing the urine out.
