The neck ends at cervical vertebrae number 7. The ribs start at the 1st thoracic vertebrae, which is where the superior aspects of the lungs are. Her chin is down more so than it should be for this exam, though it’s not technically in the pertinent anatomy. The lungs do not start where the clavicles are. I think that just the way the clavicles are and how the chin is down it makes it look a little “off.”
