Verified step by step guidance1
Begin by understanding the anatomical terms related to limb movement. These terms describe the direction and plane in which a limb moves.
Identify the term 'Abduction'. Abduction refers to the movement of a limb away from the midline of the body. This is a lateral movement, such as raising the arms or legs sideways.
Contrast 'Abduction' with 'Adduction'. Adduction is the movement of a limb toward the midline of the body, opposite to abduction.
Consider 'Extension' and 'Flexion'. Extension refers to increasing the angle between body parts, while flexion refers to decreasing the angle, neither of which specifically involves moving away from the midline.
Conclude that the correct term for the movement of a limb away from the midline is 'Abduction', as it specifically describes lateral movement away from the body's center.
