Which of the following suffixes indicates an examination?

The suffix that indicates an examination is "-scopy." This suffix is derived from the Greek word "skopein," which means "to look" or "to examine." It is commonly used in medical terminology to refer to the process of visually examining an internal body part or organ, often using a specialized instrument. For example, "endoscopy" involves examining the interior of a hollow organ through an endoscope.

In contrast, the suffix "-gram" refers to a record or a writing resulting from a procedure, such as in "radiogram," which indicates an image produced by radiography, not an examination itself. The suffix "-ptosis" denotes a falling or drooping, usually used in the context of the body, such as in "nephroptosis," which refers to the displacement of a kidney. Lastly, "-plegia" means paralysis or loss of movement, as seen in terms like "quadriplegia," describing paralysis of all four limbs. Each of these suffixes has distinct meanings, while "-scopy" specifically relates to the act of examination.
