The cell membrane of a neuron is semi-insulating and about 6 nm thick. Axons in the peripheral nervous system are sheathed in a layer of insulating myelin formed by Schwann cells. The insulating myelin is ~300 times thicker than a single phospholipid bilayer. At the same resting potential of -70 mV, what is true about the myelinated axon compared to the unmyelinated phospholipid bilayer? The myelinated axon:
capacitance/area, surface charge density, energy stored
A. Lower, lower, lower
B. Lower, lower, higher
C. Lower, higher, higher
D. Higher, higher, higher
E. Higher, lower, lower
