To measure the resting potential of a neuron,a physiologist would place
A)two electrodes inside the neuron.
B)one microelecrode inside the neuron and another in the interstitial fluid.
C)one electrode inside the cell and another inside another cell.
D)one electrode inside the cell and another outside the body.

Question

Quizplus · Accepted Answer

To measure the resting potential of a neuron, one microelectrode would be placed inside the neuron while another would be placed in the interstitial fluid surrounding the neuron. This allows for accurate measurement of the potential difference between the inside and outside of the neuron. Placing two electrodes inside the neuron (A) or one electrode inside the cell and another inside another cell (C) would not accurately measure the resting potential. Placing one electrode inside the cell and another outside the body (D) would measure the resting potential and other potentials from neighboring cells, leading to inaccurate results. Therefore, (B) is the best choice.
