The pectineal line has which structure attached to it?

• A. Pectineal Ligament
• B. Iliopsoas Tendon
• C. Inguinal Ligament
• D. Obturator Membrane

Answer: (A)

The pectineal line on the pubic region is where the pectineal (Cooper’s) ligament anchors. This ligament is a thickened fascia that runs along the pectineal line, forming part of the posterior boundary of the femoral canal and linking the lacunar ligament to the femoral ring. That attachment is why this line is described as the site for the pectineal ligament. The other structures don’t attach here: the iliopsoas tendon inserts on the lesser trochanter of the femur, not along the pectineal line; the inguinal ligament extends from the ASIS to the pubic tubercle, not along this line; the obturator membrane covers the obturator foramen and attaches around its margins, not to the pectineal line.
