What is the meaning of the suffix "-gram"?

• A. To record
• B. Procedure or process
• C. Measurement
• D. Examination

Answer: (A)

The suffix "-gram" refers to a written record or a graphical representation of data. In medical terminology, it indicates that something has been recorded or depicted, often in the context of imaging or documentation of physiological data. For example, in terms like "radiogram" (an image produced by radiography) or "electrocardiogram" (the recording of electrical activity of the heart), the "-gram" suffix signifies that a specific type of recording has taken place.

The other options present different meanings. "Procedure or process" pertains to actions taken in a medical context, while "measurement" relates to quantifying dimensions or levels of certain parameters. "Examination" involves the assessment or inspection of a patient’s condition or the interpretation of data which is not directly tied to the concept of recording. Thus, the definition of "-gram" as a record aligns precisely with its use in medical terminology.
