The pectineal line has attachments to which ligament?

The pectineal line has attachments to which ligament?

• A. Anterior Superior Iliac Spine
• B. Sacrospinous Ligament
• C. Iliofemoral Ligament
• D. Pectineal Ligament

Answer: (D)

The pectineal line is a ridge on the superior pubic ramus where the thickened fascia forms the pectineal (Cooper’s) ligament. This ligament runs along the pectineal line, anchoring there to reinforce the posterior boundary of the femoral canal and the inguinal region. That direct attachment is why the pectineal line has the pectineal ligament as its associated ligament. The other structures listed do not attach to this line: the anterior superior iliac spine is a landmark for other muscles and ligaments, the sacrospinous ligament spans from sacrum to ischial spine, and the iliofemoral ligament extends from the ilium to the femur and does not contact the pectineal line.
