The term meaning 'elbow' is.

• A. Cutaneous
• B. Cubitus
• C. Cost(o)
• D. Cyan(o)

Answer: (B)

This tests your ability to recognize anatomical roots that name body parts. The elbow is named by the Latin root cubitus, which forms terms like cubital or cubitus region to describe that area. That’s why cubitus is the best answer in this set. Cutaneous means skin, cost(o) relates to ribs (costal), and cyan(o) means blue (as in cyanosis), so they describe other structures or color changes rather than the elbow itself. In clinical language you’ll also see forms like antecubital to refer to the front of the elbow, reinforcing that cubitus denotes the elbow.
