Model description of tissue block EX07. Left panel: Cleavage plane angles (β') computed for the base-apex section shown in Fig. 2 upper-left, on a 30 × 30 grid. Middle panel: Cleavage plane angles (β") computed from serial circumferential plane (X1-X3) sections, mapped to the same base-apex plane as in A. Each row of angles is derived from a single circumferential plane tissue section, along its edge that abuts the base-apex plane section. Grayed boxes in the grids of both β' and β" panels represent areas of indeterminate cleavage plane angle. Right panel: Graph of the full model description including the transmural dependence of myofibre angle (line), from epicardium (epi) to endocardium (endo), and transmural distribution of sheet angles (β; dots) as derived from the β' and β" fields. The transmural thickness of the tissue block (20.55 mm) is shown at the bottom-right corner of the graph.
