E)millivolts.

Question

Quizplus · Accepted Answer

The electrical difference across a neuronal membrane is commonly referred to as the membrane potential, which is measured in millivolts (mV). This potential arises from the separation of charged ions across the membrane, and is maintained by the activity of ion channels, pumps, and exchangers. Newtons measure force, milliwatts measure power, joules measure energy, and milliamperes measure electrical current, none of which are suitable for measuring the membrane potential.
