Surface Landmarks of Abdomen and Thorax

The inferior angle of the scapula in anatomical position corresponds to which rib or intercostal space?

A 28-year-old man presents to the trauma bay after a motor vehicle accident. On primary survey, the clinician performs a rapid assessment of the thorax and notes that breath sounds are absent on the right side. To localize the injury and guide further imaging, the examiner identifies the 2nd rib by palpating a bony prominence at the level of the sternal angle (angle of Louis). Counting downward from this landmark, the clinician determines that the right mainstem bronchus is likely at the level of which rib?

At which level does the transpyloric plane intersect the anterior abdominal wall?

A 32-year-old woman presents to the emergency department with acute onset right upper quadrant pain and tenderness.
