The morpheme -gram generally means:

• A. Record
• B. Visual
• C. Process
• D. Light

Answer: (A)

The important idea here is that the suffix -gram signals a record or written image produced by a test or device. In medical terms, it refers to the result you obtain—the trace, image, or recording of what was measured. For example, a mammogram is the image produced to examine the breast; an electrocardiogram is the recording of the heart’s electrical activity; an angiogram is the image of the blood vessels captured from a study. So -gram essentially means a recorded result, a written or graphical record, which is why it best aligns with “Record.” Noting the distinction, another suffix like -graph would point more to the instrument or act of recording (for instance, the device that records), while -gram emphasizes the recorded output itself.
