Anatomical terminology

In human anatomy, the inguinal triangle is a region of the abdominal wall. It is also known by the eponym Hesselbach's triangle, after Franz Kaspar Hesselbach.[1]


It is defined by the following structures:[2]

This can be remembered by the mnemonic RIP (Rectus sheath (lateral border), Inferior epigastric artery, Poupart's ligament (inguinal ligament)).

Clinical significance[edit]

The inguinal triangle contains a depression referred to as the medial inguinal fossa, through which direct inguinal hernias protrude through the abdominal wall.[3]
