During the transmission of nerve impulse through a nerve fibre, the potential on the innerside of the plasma membrane has which type of electric charge?

Options

  1. AFirst negative then positive and again back to negative
  2. BFirst positive then negative and continue to be negative
  3. CFirst negative then positive and continue to be positive
  4. DFirst positive then negative and again back to positive

Correct answer

A. First negative then positive and again back to negative
