Freeze-Fracture EM, Nervous tissue, x 45,000 (#1-1)
The protoplasmic face (P) of a cell membrane is shown in the center of the micrograph. Numerous proteins embedded in the lipid bilayer may be seen. Note the smoother appearance of the external face (E) of the adjacent cell, seen at the bottom of the picture.
