KROK 1 2015 – Question 172 · KROK (Medicine) · Physiology
Microelectrode analysis of nerve fiber bioelectrical activity revealed, that its membrane potential equals −90 mV. Its initial rest potential was −85 mV. What process occurs in this case?
- A. Depolarization
- B. Hyperpolarization
- C. Repolarization
- D. Supernormality
- E. Overshoot
Hint
Compare the new membrane potential with the original resting value and decide in which direction, relative to zero, the potential has shifted.
The answer, the explanation and a note on every option are available once you log in. The account is free: topic tests, a mock exam, mistake review and statistics.
