Inguinal triangle is labeled in green. Borders: inferior epigastric artery and vein: labeled at center left, and run from upper right to bottom center. inguinal ligament: not labeled on diagram, but runs a similar path to the inguinal aponeurotic falx, labeled at bottom. rectus abdominis muscle: runs from upper left to bottom left. 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.

Structure

It is defined by the following structures:

Medial border: Lateral margin of the rectus sheath.
Superolateral border: Inferior epigastric vessels.
Inferior border: Inguinal ligament.

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

Clinical significance

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

History

The inguinal triangle is also known as Hesselbach's triangle, after Franz Kaspar Hesselbach.
