WebbThe plasma membrane of the neuron is highly permeable to K +, and in fact the recorded membrane potential of most neurons (−60 to −75 mV) is close to that predicted by the Nernst equation for K +. However, it is not exactly the same, because K + is not the only ion affecting the membrane potential. WebbThe plasma membrane Underneath the cell wall lies the plasma membrane. The basic building block of the plasma membrane is the phospholipid, a lipid composed of a glycerol molecule attached a hydrophilic (water-attracting) phosphate head and to two hydrophobic (water-repelling) fatty acid tails.
