Detailed explanation-1: -The urethral sphincters are two muscles used to control the exit of urine in the urinary bladder through the urethra. The two muscles are either the male or female external urethral sphincter and the internal urethral sphincter . When either of these muscles contracts, the urethra is sealed shut.
Detailed explanation-2: -The internal urethral sphincter regulates involuntary control of urine flow from the bladder to the urethra, and the external urethral sphincter provides voluntary control of urine flow from the bladder to the urethra.
Detailed explanation-3: -The internal urethral sphincter relaxes, allowing for urine to pass out of the bladder into the urethra.
Detailed explanation-4: -The wall of the bladder is comprised of smooth muscle fibers oriented in multiple different directions. These smooth muscle fibers are collectively known as the detrusor muscle.
