Which of the following describes -itis?

Specific study or practice
Condition indicating a tumor
Refers to inflammation
Fear of specific things

The correct answer is: Refers to inflammation

The correct answer is that -itis refers to inflammation. In medical terminology, the suffix "-itis" is commonly used to denote an inflammatory condition affecting various body parts. For example, "arthritis" indicates inflammation of the joints, while "sinusitis" refers to inflammation of the sinuses. This suffix helps convey important information about the nature of the condition, specifically that it involves an inflammatory response. The other options represent different concepts within medical terminology. The prefix regarding specific study or practices relates more closely to "-ology," which indicates a field of study (such as "physiology"). A condition indicating a tumor typically uses the suffix "-oma," which denotes neoplasia or abnormal mass growth. Fear of specific things is termed with the suffix "-phobia," indicating an irrational fear associated with particular situations or objects.
