Pain; painful condition?

• A. Acr/o
• B. Skeletal System
• C. Osteoblast
• D. Algia

Answer: (D)

Suffixes in medical terminology can signal what a condition involves. Pain is signified by the suffix -algia, which comes from a root meaning pain. This ending turns a topic into a description of a painful condition, as in neuralgia (nerve pain) or gastralgia (stomach pain). The term that means pain or a painful condition here is Algia. The other options don’t express pain: Acr/o is a combining form related to extremities or height, not pain; Skeletal System refers to a body system, not a suffix or concept of pain; Osteoblast is a bone-forming cell, again unrelated to pain.
