Question

"Movement of the arm toward midline is referred to as:

a) flexion.
b) extension.
adduction.
abduction."

Answer 1

Abduction is the movement of a bone away from the midline of the body, while adduction is the movement of a bone toward the midline.

Step-by-step explanation:

Abduction occurs when a bone moves away from the midline of the body. Examples of abduction are moving the arms or legs laterally to lift them straight out to the side. Adduction is the movement of a bone toward the midline of the body. Movement of the limbs inward after abduction is an example of adduction. Circumduction is the movement of a limb in a circular motion, as in moving the arm in a circular motion.
