Which structure attaches to the anterior superior iliac spine?

• A. Inguinal ligament
• B. Tensor fascia latae
• C. Gluteus medius
• D. Iliacus

Answer: (A)

The anterior superior iliac spine is a key anchor point for the inguinal ligament. This thickened band of the external oblique aponeurosis runs from the ASIS to the pubic tubercle, forming the lower border of the external oblique and marking the groin region. Because the ligament literally attaches at the ASIS and travels medially to the pubic tubercle, it’s the structure most characteristically described as attaching there. (For context, while other structures may originate near the ASIS, the inguinal ligament is the classic attachment that uses ASIS as its starting point.)
