Which term refers to drawing toward the midline of the body?

• A. Abduction
• B. Adduction
• C. Flexion
• D. Extension

Answer: (B)

Drawing toward the midline of the body is adduction. The midline is an imaginary line that runs down the center of the body, separating left and right sides. When a limb is moved toward that line, you adduct it—for example, bringing the arms down to the sides or bringing the fingers together. By contrast, moving away from the midline is abduction. Flexion and extension describe changes in joint angle (bending or straightening) rather than toward or away from the midline, with flexion decreasing the angle and extension increasing it.
