I have received a few excellent journal articles recently discussing the diaphragm! If you are interested in reading more about the anatomy of the diaphragm, and the role of the diaphram (more than just respiration), then be sure to check out these new references. They have been added to the PRI Library, as well as the reference list for the Postural Respiration course. And, the best news of all is that they are all available as Free PDF's online (see links below). Enjoy!
