Question

The membrane of an unstimulated neuron is unpolarised.


  1. True

  2. False


Solution

The correct option is B

False


The membrane of an unstimulated neuron is polarised—that is, there is a difference in electrical charge between the outside and inside of the membrane. In the normal resting condition, the outer side of the nerve fiber carries a positive charge, due to the presence of more Na+ ions outside the axon membrane.
