What does the prefix retro- indicate in medical terminology?

Explanation:
Retro- indicates behind or backward in location or direction. It’s used to describe structures that sit behind another reference point or movements that go in a backward direction. For example, retroperitoneal means located behind the peritoneum; retroflexion refers to bending backward; retrograde describes moving backward along a normal flow. Other directional ideas are expressed with different prefixes: ahead implies in front, across or through uses trans- (or similar), and outside uses ecto- or exo-. Because retro- specifically conveys behind, it’s the most accurate choice.
