Which of these is true when a neuron is at rest?
Correct answer: A. The outside is positive
- A. The outside is positive
- B. The outside is negative
- C. There is no voltage
- D. The inside is positive
Explanation
A neuron at rest is negatively charged inside : the inside of a cell is approximately 70 millivolts more negative than the outside and outside is positively charged.

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.
