Abductor muscles is antagonist of

Options

A. Adductor
B. Flexor
C. Pronator
D. Rotator

Answer

**Step-by-Step Solution:**

1. **Understanding Muscle Groups**: First, we need to understand the different types of muscles mentioned in the options. The abductor muscles are responsible for moving a limb away from the midline of the body.

2. **Identifying the Opposite Function**: The term "antagonist" in muscle physiology refers to a muscle that opposes the action of another muscle. Since abductors move limbs away from the midline, we need to identify which muscle group brings limbs back towards the midline.

3. **Recognizing the Adductor Muscles**: The muscles that bring limbs towards the midline are known as adductor muscles. Therefore, they perform the opposite action to that of the abductor muscles.

4. **Conclusion**: Since the abductor muscles and adductor muscles have opposing functions, we can conclude that the abductor muscles are antagonists to the adductor muscles.

5. **Final Answer**: The correct answer is adductor.
