What structure forms the floor of the inguinal canal?

• A. Pectineal ligament
• B. Inguinal ligament
• C. Fascia transversalis
• D. Iliopsoas tendon

Answer: (B)

The floor of the inguinal canal is formed by the inguinal ligament. This structure is the inferior border of the external oblique aponeurosis, running from the anterior superior iliac spine to the pubic tubercle, and the canal itself lies just above it, extending from the deep (internal) to the superficial inguinal rings. Medially, the lacunar ligament helps reinforce this floor, but the primary element making up the floor is the inguinal ligament. The fascia transversalis creates the posterior wall rather than the floor, the pectineal (Cooper) ligament is associated with the femoral region, and the iliopsoas tendon is not part of the inguinal canal floor.
