1. Why are Na+, K+, and Clâ the only ions considered in the GK equation when calculating resting membrane potential (Vm)?
A. These ions are found in the highest concentrations inside the cell
B. These are the ions to which cell membranes are permeable at rest
C. Only these ions have enough charge to influence Vm
D. These ions bind to receptors that increase the charge on the membrane
2. Voltage-regulated channels are located
A. on the neuron cell body only
B. within the cytosol only
C. in the membranes of axons only
D. in the membranes of dendrites only
E. in the membranes of dendrites, in the membranes of axons, and on the neuron cell body
3. As the charge on the membrane of a typical neuron approaches 0 from -70 mV, the cell is
A. hyperpolarizing and becoming more difficult to stimulate
B. only becoming more difficult to stimulate
C. only hyperpolarizing
D. only depolarizing
E. only repolarizing
