What does an abductor muscle do?

1. Contracts and moves towards the body

2. Contracts and moves away from the body

3. Stabilizes the body

4. Flexes the muscles

The correct answer is: Contracts and moves away from the body

An abductor muscle is responsible for moving a part of the body away from the midline. This means that when the abductor muscle contracts, it pulls the limb or body part away from the center of the body, facilitating movements like lifting your arms sideways or spreading your fingers. This action is important in many physical activities and exercises. Understanding how abductor muscles work is essential in various fields, including anatomy, physiology, and physical therapy, as it provides insights into how movements are performed and how to effectively target certain muscle groups during therapy or strength training. The role of abductor muscles is significant since they contribute to maintaining balance, stability, and proper posture during movement.
