Which of the following is TRUE about propagated nerve action potential?
(A) Decremental (B) Not affected by hypoxia (C) Fastest in C fibers (D) Not affected by membrane capacitance
(B) Acute and chronic hypoxias are associated with reduced nerve conduction velocity, neuronal action potential generation and axonal transport. In the central neurons, the reduction of nerve cell excitability in hypoxia is primarily because of increased K+ conductance. So, hypoxia also affects action potential. But compared to other statements, its can be the answer.
