Figures 14-15a, b. Freeze-fracture replicas of a muscle fiber. Figure 14. The cleavage plan exposes the P face of the cell membrane and runs through a longitudinal ridge (r) thus exposing a band of cytoplasm (c). The replica shows a large array of polygonal gap junctional plaques, intercalated with particle-free aisles. Scale bar: ^m (44,000X). Figures 15a, b. Complementary freeze-fracture replicas of part of the junction of Figure 14. E-face particles (Fig. 15a) correspond to a honeycomb array of pits on the P-face (Fig. 15b) (framed area in Fig. 14). Scale bar: ^m (100,000X)..
