Which term pertains to the cerebellum?

• A. cerebr/o
• B. cerebell/o
• C. poster/o
• D. dors/o

Answer: (B)

The combining form cerebell/o refers to the cerebellum. In medical terms, different brain parts have specific combining forms: cerebr/o for the cerebrum, cerebell/o for the cerebellum, poster/o for the back, and dors/o for the back/dorsal area. The cerebellum sits at the back of the brain and coordinates movement, balance, and posture. That makes cerebell/o the correct base for terms related to the cerebellum, such as cerebellar or cerebellitis. The other forms point to other brain regions or directions, not to the cerebellum itself.
