Which muscle originates on the ischium and pubis and inserts on the entire linea aspera and adductor tubercle?

• A. Adductor Longus
• B. Adductor Magnus
• C. Pectineus
• D. Gracilis

Answer: (B)

Adductor magnus. It has a broad origin from the inferior pubic ramus and ischial ramus (with a hamstring part from the ischial tuberosity) and it inserts along the entire linea aspera and onto the adductor tubercle of the femur. This broad insertion pattern, combining the linea aspera and the adductor tubercle, is distinctive. In contrast, the adductor longus attaches to the middle third of the linea aspera, the pectineus to the pectineal line, and gracilis to the medial tibia.
