Which aspect of the action potential will most likely be affected by the injection of TTX?
A) Depolarization due to K+ channel blockade
B) Depolarization due to Na+ channel blockade
C) Depolarization due to Na+ channel opening
D) Hyperpolarization due to K+ channel blockade
E) Hyperpolarization due to Na+ channel blockade
