Figure 2: Cross-sections of a PVA model urethra with a Y-shaped opening (a) and of the proximal part of the male pig urethra (b). We stained elastin, collagen (both dark grey) and muscle tissue (light grey) using elastin von Gieson staining. The lamina propria is surrounded by muscular tissue with a horseshoe-like shape. Panel b was reproduced from Urodinamica 16, 310-320, 2006, with kind permission from Editrice Kurtis.
