During the action potential, just after __________ ions enter the axon, __________ ions leave, restoring the original charge.
A) sodium...potassium
B) potassium...hydrogen
C) sodium...other sodium
D) potassium...other potassium
Sodium Ions
Electrically charged particles of sodium that play crucial roles in physiological processes, including nerve impulse transmission and muscle contraction.
Potassium Ions
Charged particles of potassium that are crucial for various bodily functions, including nerve impulse transmission and muscle contraction.

Final Answer :
A
Explanation :
During an action potential, sodium ions enter the axon, causing depolarization. This is followed by the exit of potassium ions, which restores the original charge through repolarization. Therefore, option A (sodium...potassium) is the correct choice.
