Question

An organ with sphincters at its origin is ______.

Options

• urethra

• ureter

• renal pelvic

Answer 1

An organ with sphincters at its origin is urethra.

Explanation:

Urine leakage is prevented by the smooth muscle internal urethral sphincter, which is situated at the bladder neck/origin of the urethra. The ureters attach to the bladder instead of starting with a separate anatomical sphincter, and the bladder itself serves as a holding tank.
