During resting membrane potential condition:
Correct answer: A. Outer surface of neuron is more positive
- A. Outer surface of neuron is more positive
- B. Inner surface of neuron is more positive
- C. Both of these surfaces are equally positive
- D. Both of these surfaces are equally negative
Explanation
The outer surface is more positive than the inside due to a greater quantity of +ve ions in the outer environment.

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.
