Foramen of Morgagni

Dr Tim Luijkx and Dr Craig Hacking et al.

The foramina of Morgagni, also known as the sternocostal triangles, are small defects in the posterior aspect of the anterior thoracic wall between the sternal and costal attachments of the diaphragm. The internal thoracic vessels descend through these foramina to become the superior epigastric vessels.
