    Internal intercostal muscles also known as intercostalis internus aid in forced expiration (quiet expiration is a passive process). They originate on ribs 2–12 and have their insertions on ribs 1–11.Their fibers pass anterior and superior from the upper margin of the rib and costal cartilage to the lower margin of the rib above.

    It is present only in the middle of each intercostal space, and often not present higher up the rib cage. [3] It lies deep to the plane that contains the intercostal nerves and intercostal vessels, and the internal intercostal muscles. [3] [4] The diaphragm is continuous with the innermost intercostal muscle. [5]
