|Artery: Musculophrenic artery|
|(Musculophrenic artery labeled at center left.)|

|Source||Internal mammary artery|
|Branches||Lower Pericardium, Diaphragm, and Abdominal muscles|
The Musculophrenic Artery arises from the internal thoracic artery, directed obliquely downward and lateralward, behind the cartilages of the false ribs; it perforates the diaphragm at the eighth or ninth costal cartilage, and ends, considerably reduced in size, opposite the last intercostal space.
It gives off intercostal branches to the seventh, eighth, and ninth intercostal spaces; these diminish in size as the spaces decrease in length, and are distributed in a manner precisely similar to the intercostal arteries from the internal thoracic artery.
