The combining form cyst/o denotes which anatomical structure?

• A. Glans penis
• B. Epididymis
• C. Urinary bladder, sac
• D. Kidney

Answer: (C)

The combining form cyst/o denotes the urinary bladder, the sac that stores urine. This root appears in terms such as cystoscopy (looking into the bladder), cystitis (inflammation of the bladder), and cystography (imaging of the bladder). While cyst/o can refer to a sac in a broader sense, in urology it most commonly points to the urinary bladder. The other structures are described by different roots: glans penis by balan/o or glan/o, epididymis by epididym/o, and the kidney by nephr/o or ren/o.
