Which of the following muscle types moves a part of the body towards the body's midline?

1. Abductor

2. Extender

3. Adductor

4. Flexor

The correct answer is: Adductor

The muscle type that moves a part of the body towards the body's midline is the adductor. Adductors are responsible for bringing limbs or other body parts closer to the midline, which is the imaginary line that divides the body into equal right and left halves. For example, in the case of the legs, the adductor muscles work to bring the legs together. In contrast, the abductor muscles serve to move limbs away from the midline, such as raising the arms or legs outward. Extender muscles focus on increasing the angle at joints, which moves a body part away from its relaxed position, and flexor muscles decrease the angle at joints, bringing body parts closer together but not towards the midline. Therefore, the adductor muscle specifically fulfills the role of moving parts of the body towards the midline, making it the correct answer.
