The prefix bleph means which of the following?

• A. Arm
• B. Life
• C. Eye lid
• D. Pressure

Answer: (C)

Prefixes in medical terminology tell you which body part is involved. Bleph- comes from a Greek word meaning eyelid, so it flags terms related to the eyelid itself. That’s why it’s used in words like blepharitis (inflammation of the eyelid), blepharoplasty (surgical repair of the eyelid), and blepharoptosis (drooping of the eyelid). The other options refer to different ideas—arm, life, or pressure—and don’t relate to the eyelid, so they don’t fit. An easy way to remember is to connect bleph- with eyelid conditions and procedures.
