D) a capacity to reabsorb neurotransmitter molecules released into the synaptic gap.

Question

Quizplus · Accepted Answer

The resting potential of a neuron refers to the electrical polarization of the inside and outside of the neural membrane, which is typically around -70 millivolts. This means that the inside of the neuron is negatively charged relative to the outside. This polarity is maintained by the selective permeability of the neural membrane, which allows certain ions (such as potassium and sodium) to pass through while preventing others from doing so. This polarization sets up the conditions for neural communication to occur, as electrical signals can be generated when the neuron is stimulated in the right way.
