What does the prefix trans- indicate in medical terminology?

Explanation:
Trans- indicates across or through, a directional modifier used when a term describes moving across a barrier or from one side to the other. You can see it in transdermal, which means moving across the skin, or transfusion, which involves transferring something from one person to another. The core idea is crossing or passing through, which is exactly what this prefix communicates. Other directional prefixes describe location relative to a barrier (behind, within, outside) but they do not convey crossing, so they don’t fit as well.
