Which term demonstrates the RETRO- prefix meaning behind or backward?

• A. Retrograde
• B. Posture
• C. Transverse
• D. Antegrade

Answer: (A)

Understanding direction prefixes in medical terms helps you decode meaning quickly. The retro- prefix means backward, behind, or in reverse. A term that uses this prefix to describe movement in the backward direction is retrograde, which literally means moving backward or occurring in reverse. In medical contexts you might see retrograde flow or retrograde motion, illustrating that reverse direction idea. The other words point to different directions or concepts: transverse relates to across the body, antegrade means moving forward, and posture refers to body position rather than a directional movement. So retrograde best demonstrates the meaning of retro- as backward.
