Na+ (sodium ions) are nearly _ times greater in fluid outside the cell th inside:
Correct answer: A. 10
- A. 10
- B. 30
- C. 2
- D. 3
Explanation
The concentration of Na+ ions is approximately 10 times greater in fluids outside (extracellular) the cell compared to inside (intracellular) the cell. This significant difference in ion concentration plays a crucial role in various physiological processes, such as maintaining the resting membrane potential and facilitating nerve cell function.

About Neurons and Nerve Impulse
Neurons receive and transmit information through dendrites, the cell body and axons. The topic explains resting potential, depolarization, repolarization, refractory periods and saltatory conduction, followed by synaptic transmission through neurotransmitters. An action potential is distinct from the graded potential produced at a receptor.
