Photomicrographs of bladder cross-sections confirm the results obtained with whole mounts and indicate the predominance of TRPV1 fibers in the urothelium and the predominance of ChAT fibers in the detrusor smooth muscle. A-D are representative photomicrographs of the entire bladder cross section. E-H are representative photomicrographs of the detrusor smooth muscle taken at high magnification to show some areas of overlap between ChAT and TRPV1, primarily in intramural fascicles (H). I- L are representative photomicrographs of bladder urothelium taken at high magnification to show some areas of overlap between ChAT and TRPV1, primarily in the lamina propria (sub urothelium), as illustrate (L).
