Alberta Health Services Practice Test

The root cholecyst/o means which anatomical structure?

Head Tissue Sensation Gallbladder

Correct Answer:

Gallbladder

Explanation:

Cholecyst/o is the combining form used to name the gallbladder. It comes from chole (bile) combined with cyst/o (bladder), forming terms that refer to the gallbladder itself. That’s why it appears in phrases like cholecystitis (inflammation of the gallbladder) or cholecystectomy (removal of the gallbladder). The other options point to different anatomical parts or senses: cephal/o would relate to the head, hist/o to tissue, and esthet/o (or related forms) to sensation. So cholecyst/o specifically identifies the gallbladder.
