The suffix "-scopic" is used to describe what characteristic?

The suffix "-scopic" is derived from the Greek word "skopein," which means "to look" or "to examine." Therefore, when used in medical terminology, it indicates a method related to visual examination or observation. For instance, terms like "endoscopic" refer to procedures that involve visual inspection of internal structures using an endoscope. This suffix conveys the idea of inspecting or observing something closely, making it essential in contexts where visualization is a key component of diagnosis or treatment.

The other options refer to different aspects of medical terminology: muscle function, abnormal flow, and discharge, which all relate to specific medical conditions or processes but do not involve the visual examination implied by "-scopic." The focus on inspection distinguishes the correct choice clearly.
