Question

If there is a difference in electrical charge between the outside and inside of the membrane, the neuron is ___

• A. Depolarised
• B. Polarised
• C. Stimulated
• D. Neutralised

Answer 1

The correct option is B

Polarised

Neurons are highly polarised cells with structurally and functionally distinct processes called axons and dendrites. This polarisation explains the directional flow of information in the central nervous system. The transmission of a nerve impulse along a neuron from one end to the other occurs as a result of electrical changes across the membrane of the neuron.
