When a neuron is polarized?

When a neuron is polarized, it means that there is a difference in electrical charge across its membrane, with the inside of the cell being more negatively charged compared to the outside. This polarization is primarily due to the distribution of ions, particularly sodium (Na+) and potassium (K+), maintained by the sodium-potassium pump. This resting potential is crucial for the neuron's ability to generate action potentials and transmit signals. In this state, the neuron is ready to respond to stimuli.
