Which term means arm?

• A. Brachi/o
• B. Mandibul/o
• C. Ophthalm/o
• D. Pulmon/o

Answer: (A)

Understanding combining forms for body parts helps decode medical terms. Brachi/o specifically means arm, and you’ll see it in words like brachial artery or brachial plexus, which both refer to structures in the upper limb. The other options point to different parts: mandibul/o is the jaw, ophthalm/o is the eye, and pulmon/o is the lung. So the term that means arm is brachi/o.
