Heightened sensitivity to a neurotransmitter after the destruction of an incoming axon is known as ____.
A) axon supersensitivity
B) disuse supersensitivity
C) enervation supersensitivity
D) denervation supersensitivity

Question

Quizplus · Accepted Answer

Denervation supersensitivity refers to the increased sensitivity of postsynaptic receptors to a neurotransmitter after the destruction of the incoming axon. This can occur due to a lack of inhibition from the destroyed axon, leading to an upregulation of receptors to compensate for the decreased neurotransmitter input.
