The pubic tubercle has which structure attached to it?

• A. Iliopsoas Tendon
• B. Lacunar Ligament
• C. Inguinal Ligament
• D. Round Ligament

Answer: (C)

The pubic tubercle marks the medial end of the inguinal ligament, which runs from the anterior superior iliac spine to the pubic tubercle and forms the base of the inguinal canal. Because of this, the structure that attaches at the pubic tubercle is the inguinal ligament. The other options don’t attach there: the iliopsoas tendon attaches to the lesser trochanter, the lacunar ligament is an extension of the inguinal ligament that runs along the pectineal line near the pubic crest, and the round ligament travels from the uterus through the inguinal canal but does not anchor to the pubic tubercle.
