Propagation of Action Potentials
Multiple Choice
Dr. Roberts is testing a new drug that blocks sodium channels in the axons of a neuron. Which of the following statements is correct?
A
The drug would prevent both the generation of graded potentials and the propagation of action potentials.
B
The drug would prevent the generation of graded potentials.
C
The drug would prevent the propagation of action potentials.
D
The drug would only have a mild effect on the neuron because potassium channels are still operational.
