The internal thoracic artery (ITA), also known as the internal mammary artery, is an artery that supplies the anterior chest wall and the breasts. [1] It is a paired artery, with one running along each side of the sternum , to continue after its bifurcation as the superior epigastric and musculophrenic arteries .

The perforating branches of the internal thoracic artery pierce through the internal intercostal muscles of the superior six intercostal spaces. These small arteries run with the anterior cutaneous branches of the intercostal nerves .
The sternalis muscle is an anatomical variation that lies in front of the sternal end of the pectoralis major runs along the anterior aspect of the body of the sternum. The sternalis muscle often originates from the upper part of the sternum and can display varying insertions such as the pectoral fascia , lower ribs , costal cartilages , rectus ...

The pericardiacophrenic arteries travel through the thoracic cavity. They course through the fibrous pericardium. [2] The pericardiacophrenic artery accompanies the phrenic nerve between the pleura and pericardium, to the diaphragm. [3] This is where both the artery and the phrenic nerve are distributed.
In human anatomy, the superior epigastric artery is a terminal [1] branch of the internal thoracic artery that provides arterial supply to the abdominal wall, and upper rectus abdominis muscle. It enters the rectus sheath to descend upon the inner surface of the rectus abdominis muscle. It ends by anastomosing with the inferior epigastric artery.
