APPLIED RADIOLOGICAL ANATOMY

Detailed explanation-1: -Abduction of the wrist, moving the hand away from the body at the wrist when that arm is at the person’s side, is called radial deviation. Any muscle that creates this type of motion is termed an abductor.

Detailed explanation-2: -Abduction refers to a motion that pulls a structure or part away from the midline of the body. In the case of fingers and toes, it refers to spreading the digits apart, away from the centerline of the hand or foot.

Detailed explanation-3: -Dropping the arms to the sides, and bringing the knees together, are examples of adduction. Adduction of the wrist is also known as ulnar deviation which moves the hand towards the ulnar styloid (or, towards the little finger).

Detailed explanation-4: -Abduction is the opposite of adduction. With abduction, limbs (arms, legs or fingers) are moved away from your body’s midline. Adduction, however, refers to moving your limbs closer to the midline.
