Set out like a textbook diagram in relief, this cell membrane cutaway shows the lipid bilayer running across the middle with embedded channel proteins. Above and below the membrane sit raised ions marked with plus and minus symbols, with small arrows showing ions passing through the channels. The layout illustrates how potassium inside and sodium outside set the resting membrane potential. Flat on the back and solid in form, it suits a classroom wall, a teacher's desk or a bioelectricity study display.
