Posterior intercostal arteries are the arteries that supply the blood to the intercostal spaces together with their anterior counterpart. Origin Posterior intercostal arteries originate as: The 1st and 2nd posterior intercostal arteries are the divisions of superior intercostal artery which is a branch of the costocervical trunk.
Intercostal Arteries
Posterior and anterior intercostal arteries are responsible for the blood supply. Blood supply is abundant in the thoracic wall. 1 posterior and 2 anterior intercostal arteries (upper and lower) are included in every intercostal spaces. Posterior Intercostal Arteries There are 11 pairs of intercostal arteries, 1 in
Anterior Intercostal Arteries
The anterior intercostal arteries arise as lateral divisions from the internal thoracic arteries either directly or indirectly. Anterior intercostal arteries which circulate the upper six intercostal spaces emerge as lateral branches from the internal thoracic artery, while those circulating towards the lower spaces arise via the musculophrenic

The two internal thoracic arteries can be differentiated as left and right. One on the either side of sternum and is located deep towards the anterior chest wall. Origin The initial part of the subclavian artery (lower surface) is the source of the internal thoracic artery situated
