What is a typical value for the resting membrane potential of a neuron?
Correct answer: A. -70 mV
- A. -70 mV
- B. -120 mV
- C. 0.05 V
- D. Both Options A and B are correct
Explanation
The resting membrane potential of a neuron is about -70 mV. The negative sign means that the inside of the neuron is 70 mV less than the outside voltage.

About Coordination and Control
Coordination depends on receptors, neurons, synapses and nerve impulses, with reflex actions traced through the reflex arc and the roles of major brain regions. Chemical coordination covers endocrine glands and hormones, including how hormones regulate growth, metabolism, reproduction and internal balance, unlike rapid nervous control.
