What action does the adductor magnus (adductor/lateral) perform?

• A. Adductor and Medially Rotates Thigh
• B. Abducts Thigh
• C. Extends Thigh
• D. Laterally Rotates Thigh

Answer: (A)

Adductor magnus has two functional parts and acts mainly to bring the thigh toward the midline while also medially rotating it. The anterior, or adductor, part adducts the thigh and can medially rotate the hip, especially when the thigh is flexed. The posterior, or hamstring, part extends the thigh. So the best single description is that this muscle adducts the thigh and medially rotates it. It is not a primary abductor or lateral rotator, and thigh extension is a feature of the posterior part rather than the overall primary action.
