Adductor muscle: Any muscle that pulls a body part toward the midline. For example, the adductor muscles of the legs pull the legs toward the midline of the body so the legs are closer together.
The word "adductor" comes from the Latin prefix "ad" meaning "toward" + "ducere" meaning "to draw or lead" = "to draw toward." The opposite of "adductor" is "abductor." An adductor muscle opposes an abductor muscle.
