The correct answer is:
**Movement toward a midline is *adduction* (noun). When a patient is asked to move his arm toward his body, he is asked to adduct (verb) his arm.**
Explanation:
The prefix “ad-“ comes from Latin and means “toward” or “to.” It is often used in medical and anatomical terms to describe movements or actions directed toward a central point or midline of the body.
In the context of movement:
- Adduction refers to the movement of a body part toward the midline of the body or toward another part. For example, when a person brings their arm toward the body’s midline, they are performing adduction of the arm.
- The verb form of this action is adduct, which describes the actual action of bringing the body part closer to the midline. For example, if a doctor instructs a patient to adduct their arm, they are asking the patient to move their arm toward their body.
This contrasts with the term abduction, where “ab-“ (meaning “away”) refers to moving a body part away from the midline. For example, raising the arms out to the sides away from the body is abduction of the arms.
The concept of adduction and abduction is particularly important in understanding body mechanics and physical therapy. It helps clinicians and patients describe specific movements, which are crucial in diagnosing and treating musculoskeletal conditions. These terms are widely used in orthopedics, rehabilitation, and sports medicine to assess and guide movement and recovery processes.
In summary:
- Adduction (noun): Movement toward the body’s midline.
- Adduct (verb): To move toward the midline.
