D) the electrical charge inside is negative relative to the outside

Question

Quizplus · Accepted Answer

When a neuron is polarized, the electrical charge inside the cell is negative relative to the outside. This is because there are more negatively charged ions (such as chloride) inside the cell and more positively charged ions (such as sodium) outside the cell. This difference in charge is essential for the transmission of information along the neuron.
