Which statement about the internal urethral sphincter is true?

Explanation:
The internal urethral sphincter is smooth muscle at the bladder neck that is controlled by the autonomic nervous system, so its action is involuntary. It stays tonically contracted to keep urine in and relaxes as part of the micturition reflex when pairing with detrusor contraction. This differs from the external urethral sphincter, which is skeletal muscle under voluntary control, and it is not cardiac muscle.
