Further to the current discussion I thought to share this image (a part of my shroud presentation). It shows the anatomical accuracy of the man of the shroud against a standard model. The total length being 8 heads, the 2nd head from top ends at the nipples, 3rd head to the navel, 4th head to the groin, 2 heads further reaches the bottom of the knee and so forth. Also Rigor Mortis is evident in the chest muscles. As you can see they are pulled up as if the arms were raised at time of death. The Rigor would be broken at the shoulder level but the chest muscles stayed stiff in the original raised position.
