Which receptor hyperpolarizes the axon terminal to slow or cancel the action potential when norepinephrine binds? A)a₂receptor B)fi₂receptor C)a₁receptor D)fi₃receptor

Question

Quizplus · Accepted Answer

The correct choice is A) α2-adrenergic receptor. When norepinephrine binds to the α2-adrenergic receptor, it typically results in the hyperpolarization of the axon terminal, which can slow down or inhibit the release of further neurotransmitter, effectively slowing or canceling the action potential. This mechanism is part of the body's feedback system to regulate neurotransmitter release.
