Which term is used to describe the study of a particular subject in medical terminology?

The suffix “-ology” is used in medical terminology to denote the study of a specific subject or field. It is derived from the Greek word "logia," which means "the study of" or "the science of." For instance, "neurology" refers to the study of the nervous system, and "biology" refers to the study of life and living organisms. This suffix is a fundamental component in the formation of medical terms related to various specialties within healthcare.

The other terms do not pertain to the study of a subject. “-gram” refers to a record or a picture, commonly used in contexts like “radiogram.” “-ase” pertains to enzymes, signifying a substance that catalyzes a chemical reaction, such as in “lipase.” “-itis” indicates inflammation, as seen in terms like “appendicitis” or “bronchitis.” Each of these suffixes serves a distinct function in medical nomenclature but none are used to denote the act of studying a subject.
