Which prefix denotes 'Duodenum'?

Which prefix denotes 'Duodenum'?

• A. Duodeno-
• B. Splanchn-
• C. Blast-
• D. Therap-

Answer: (A)

In medical terminology, prefixes point to the location or structure involved. The duodenum—the first section of the small intestine—uses the combining form duodeno- (also seen as duoden/o) to indicate relation to it. That makes duodeno- the correct prefix for denoting the duodenum. The other prefixes don’t indicate the duodenum: splanchn- refers to the viscera or internal organs; blast- denotes a germ or immature cell; therap- relates to treatment or therapy. So they point to different concepts rather than to the duodenum.
