homology notes

Behind the thorax, the lateral group (of muscles in reptiles and mammals) remains essentially as for amphibians. (It breaks into three sheet-like layers: external oblique muscle, the internal oblique, and the transversus). More anteriorly, however, the ribs, now enlarged, penetrate and alter this group of muscles. The transversus is excluded from the thorax and the external and internal obliques become, respectively, the external and internal intercostal muscles, which contribute to the new function of ventilation of the lungs.[well established][VHOG]
