Morphological properties and residual strain along the small intestine in rats

Figure 4 Photographs showing (A) the distributions of the opening angle and tangent rotation angle, (B) residual strains at the mucosal and serosal surfaces, (C) the residual strain gradient and (D) residual strain gradient normalised with respect to the wall thickness (h). Values are ¯x ± s. A significant variation was found along the small intestine for all variables (P < 0.001).
