abdominal external oblique muscle

The rectus abdominis and external abdominal oblique muscles are located in the 7th to 14th thoracic vertebra sections, while deep pectoral and latissimus dorsi muscles are only found in the 6th to 9th thoracic vertebrae and the long cutaneous trunci muscle is situated from the 6th to 14th thoracic vertebrae sections.

The Professor would point to a structure and mutter, "And what do you think this is?" The students, who could barely get a clear view of the crowded surgical field would throw out some half-baked answer, "Might it be the external abdominal oblique aponeurosis?" The professor would then simply point to the structure twice (the surgical equivalent of "double click") which translated into "that was both dumb and wrong; who's next?" Know your anatomy was the key.
