Which combining form is used to denote physician or medicine?

• A. Iatr/o
• B. Mening/o
• C. Stomat/o
• D. Kinesi/o

Answer: (A)

The concept being tested is recognizing the combining form that means physician or medicine. Iatr/o comes from the Greek iatros (physician, healing) and is used in medical terms to convey a relationship to medical treatment or physicians, such as iatrogenic (caused by medical treatment) or iatrophobia (fear of doctors). The other forms refer to different things: mening/o relates to the membranes around the brain and spinal cord (meninges), stomat/o to the mouth, and kinesi/o to movement. Therefore, the combining form that denotes physician or medicine is iatr/o.
