Answer:
It would block the generation of action potential in the motor neurons
Explanation:
Tetrodotoxin (TTX) is a toxic compound found in the Pufferfish which could affect the neuronal signalling in the humans.
The tetrodotoxin binds to the sodium channels present in the motor neurons in the soma region of the neuron where the binding of the tetrodotoxin to the sodium channels inhibits the inward flow of the sodium ions. The reduction in the influx of sodium ions does not change the depolarization of the cell membrane and hence action potential is not generated in the motor neuron.
Thus, It would block the generation of the action potential in the motor neurons is the correct answer.
Answer:
Explanation:
The endocrine system plays an important role in homeostasis because hormones regulate the activity of body cells. The release of hormones into the blood is controlled by a stimulus. For example, the stimulus either causes an increase or a decrease in the amount of hormone secreted. Then, the response to a stimulus changes the internal conditions and may itself become a new stimulus. This self-adjusting mechanism is called feedback regulation.

Comparison stress
