What does the suffix "oscopy" mean?

The suffix "oscopy" comes from the Greek word "skopein," which means "to look" or "to examine." Therefore, when this suffix is used in medical terminology, it indicates a visual examination of a particular body part or cavity. For example, endoscopy refers to the visual examination of the interior of a hollow organ or cavity using an endoscope.

The other options represent different medical terms but do not pertain to visual examination. Measurement is related to quantifying dimensions or quantities, disinfection refers to the process of eliminating or reducing harmful microorganisms, and incision pertains to the act of cutting into a structure. Thus, the correct understanding of "oscopy" is specifically aligned with the concept of a visual examination.
