Which muscle adducts the thigh and is commonly used in bed mobility?

• A. Adductor longus
• B. Gracilis
• C. Pectineus
• D. Sartorius

Answer: (B)

The key idea is that your bed-mobility movements often require more than just pulling the thigh inward; they benefit from a muscle that can help move the leg at both joints it spans. Gracilis fits this role because it crosses the hip and the knee, so it assists with adducting the thigh at the hip and also helps bend the knee. This dual action makes it particularly useful for repositioning in bed, such as drawing the leg toward the other leg and preparing the knee for movement. Other muscles listed mainly act as hip adductors without that knee-flexion contribution, or they emphasize other actions (like flexion, abduction, or rotation) rather than the combination needed for typical bed mobility.
