About the cover: Cover is based on a colorized MRI axial slice from the caudal pharynx in a typical lean Zucker rat. The image was acquired at the end of inspiration. The finite element mesh (yellow) is overlaid on the tissue (red) to show where the lateral and ventral pharyngeal wall and control sectors (white) were chosen. For more information, see article (and online supplement) by Brennick and colleagues beginning on page 1031.
