## Step 1<br />The first question is about the relationship between flexion and extension, which are movements that decrease and increase the angle between two bones, respectively. The question asks for the term that has a similar relationship to pronation. Pronation is the movement that turns the palm downwards, so the term that has a similar relationship to pronation is supination, which is the movement that turns the palm upwards.<br /><br />## Step 2<br />The second question is about the relationship between abduction and adduction, which are movements that move a body part away from the midline of the body and towards the midline of the body, respectively. The question asks for the term that has a similar relationship to plantar flexion. Plantar flexion is the movement that flexes the foot in the direction of the plantar surface, so the term that has a similar relationship to plantar flexion is dorsiflexion, which is the movement that flexes the foot in the direction of the dorsal surface.<br /><br />## Step 3<br />The third question is about isotonic movement, which involves the contraction of muscles and movement of a part of the body. The question asks for the term that completes the sentence. The correct term is "movement", as isotonic movement involves the contraction of muscles and movement of a part of the body.
