-
A. Sodium ions
-
B. Potassium ions
-
C. Chloride ions
-
D. Calcium ions
Explanation
The diffusion of sodium ions across the postsynaptic membrane causes it to depolarize, initiating a new action potential.
اعصابی تحریک کی ترسیل کے دوران ڈیپولرائزیشن _______ کی وجہ سے ہے؟
-
A. Outward movement of Na^+
-
B. Inward movement of Na^+
-
C. Inward movement of K^+
-
D. Outward movement of K^+
Explanation
Depolarization during the conduction of a nerve impulse is due to the inward movement of Na⁺ (sodium ions).
This influx of sodium causes the inside of the neuron to become more positively charged, triggering the action potential.
