Which term is used to describe something relating to hearing?

• A. Axillary
• B. Audiometer
• C. Auditory
• D. Audiometry

Answer: (C)

The main idea is understanding how medical terms indicate relation to a sense. The root aud- comes from Latin audire, meaning to hear. When you add the suffix -itory, you form an adjective that means relating to or connected with. So auditory is the term used to describe something relating to hearing, as in the auditory system or auditory nerves.

The other terms point to different things: axillary means related to the armpit; a audiometer is a device used to measure hearing; audiometry is the procedure of testing hearing. So auditory fits best because it directly conveys “relating to hearing.”
