Which muscle is the bed mobility adductor and appears as the third option in this list?

• A. Adductor magnus
• B. Pectineus
• C. Gracilis
• D. Obturator externus

Answer: (C)

Bed mobility relies on bringing the leg toward the midline while you adjust position, often with some knee movement. The gracilis is the long, slender muscle on the inner thigh that crosses both the hip and knee joints, so it directly adducts the hip and assists knee flexion. This combination makes it particularly useful for repositioning in bed—pulling the leg inward during rolling, scooting, or adjusting your position. The other muscles don’t fit this specific role as neatly: adductor magnus is a deeper, stronger hip adductor with broader actions; pectineus mainly acts as a hip flexor with some adduction; obturator externus mainly contributes to lateral rotation with only minor adduction. So the gracilis best fits as the bed mobility adductor.
