The external urethral sphincter is under voluntary control and can be contracted to stop urine flow when the person desires to do so. The internal urethral sphincter is involuntary and is responsible for preventing urine from leaking out of the bladder until the person is ready to urinate. The detrusor muscle is responsible for pushing urine out of the bladder during voiding. The pectineus and internal obturator muscles are not directly involved in the micturition reflex.
