Medial: the lateral border of the sternal part of the diaphragm

Lateral: the medial border of the costal part of the diaphragm

Anterior: the musculoaponeurotic plane formed by a confluence of the transversus thoracis superiorly and the transversus abdominis inferiorly

The superficial epigastric artery passes in front of the aponeurotic plane that forms the anterior border and enters the abdomen anterior to the diaphragm.<ref name=":0" />
