Situated between the ribs. = intracostal = On the inner surface of the ribs. Inter as a prefix always mean between two things whereas intra always means within. So intercostal means between two ribs and intracostal (literally) means within the rib itself. Of course within the rib is only bone so as it says above intracostal is extended to mean in the inner surface of one rib.

There complicated arrangement tells the the movement of muscle mass during evolution.
