One way to remember adduction definition is to imagine a line passing through the center of your body. Â When you move a part of your body towards this line, you are adducting, you are adding to this imaginary line.
Imagine that your hands are stretched out to the side. There are infinite ways you can bring your hands toward the mid-line of your body. You can lower your arms to your side which is called frontal plane adduction. You can also bring your hands toward the mid-line of your body like seals clapping. This is called transverse plane adduction.
