![Resting Membrane Potential Review
Fill in the blanks
1. The average resting membrane potential for a neuron is
2. This means that the inside of the neuron is
mV more
than
the outside.
3. There are more positive
ions outside the cell and more
ions inside the cell.
4. During the resting potential, all
channels are closed and both Na+
and K+
channels are open.
5. Neurons are more permeable to
ions than to
ions because the cell
membrane has more
channels.
6. The concentration gradient for Na+ favors its diffusion
the cell; while the
concentration gradient for K+ favors its diffusion
the cell.
7. Both sodium and potassium diffuse down their concentration gradients with
diffusing out of the cell and
diffusing into the cell.
8. The

sodium ions
the cell, while pumping
potassium ions
the cell.
