The abdominal wall is supplied by the follow arteries:
- superior epigastric artery
- inferior epigastric artery
- lumbar arteries
- deep circumflex iliac
Note: the inferior epigastric artery runs superiorly on the transversalis fascia and enters the arcuate line to gain the rectus sheath.
Note: the superior epigastric artery enters the rectus sheath superiorly just inferior to the 7th costal cartilage.
