In terms like adductor, which prefix indicates toward the midline?

Explanation:
Movement toward the center line of the body is described by the prefix ad-. In anatomy, an adductor muscle pulls a body part toward the midline, so the term adductor carries the idea of directing motion inward. The midline is the imaginary divider that splits the body into left and right halves, and adduction is the action of bringing something closer to that line. Other prefixes here describe different directions—dextr/o for the right side, inter- for between, and post- for after or behind—so they don’t indicate toward the midline.
