Best Answer

The urethral sphincter is broken down into two separate muscles, the internal and external sphincter muscles of the urethra.

The internal muscle is located where the urethra joins the bladder. It is under involuntary control and works by balancing the sympathetic (keeping closed) and parasympathetic (opening) nervous systems.

The second muscle is located just after the prostate gland. It is under voluntary control and works by the somatic nervous system.
