Superior intercostal artery

  • The superior intercostal artery (latin: arteria intercostalis suprema) is a branch of the costocervical trunk that supplies tissue in the upper intercostal spaces.

    The superior intercostal artery passes inferiorly between the pleura and the necks of the first and second ribs. While crossing the neck of the first rib, the superior intercostal artery divides into two posterior intercostal arteries.

    The superior intercostal artery with its branches supplies the upper two intercostal muscles and tissues.
