During the absolute refractory period, a stimulus of high intensity may trigger a nerve impulse.Group startsTrue or FalseTrue, unselectedFalse, unselected

Answering the Question

1. Understanding the Absolute Refractory Period: The absolute refractory period is a specific phase during the action potential of a neuron during which no new action potential can be initiated, regardless of the strength of the stimulus. This happens because the sodium channels are inactivated, preventing neuron depolarization.

2. Evaluating the Options: Given the definition, it becomes clear that during this period, even a strong stimulus cannot cause the neuron to fire again.

3. Conclusion: Since a stimulus of any intensity cannot trigger a nerve impulse during the absolute refractory period, the statement in question is False.

Final Answer

False: During the absolute refractory period, no stimulus, regardless of intensity, can trigger a nerve impulse.
