exif: {"Image DocumentName": "AXIS OF RIB MOTION", "Image ImageDescription": "The other change is the relationship of the axis to the coronal or frontal plane. At the first rib, this axis is almost in the coronal plane. Progressing downward the axis becomes progressively more posterior from the head of the rib. The upper ribs as they rotate about this axis move the sternum anteriorly and superiorly on inhalation. The lower ribs expand laterally, increasing the lateral diameter of the thoracic cage.", "Image XResolution": "37", "Image YResolution": "37", "Image ResolutionUnit": "Pixels/Centimeter", "Image Software": "SlidePlayer", "Image YCbCrPositioning": "Centered"}
