Denervation supersensitivity refers to an increase in:
A) production and release of neurotransmitters.
B) growth of axon branches.
C) responses to neurotransmitters.
D) polarization of the membrane at rest.

Question

Quizplus · Accepted Answer

Denervation supersensitivity occurs when a nerve loses its connections with the target organ, leading to an upregulation of receptors on the postsynaptic membrane, resulting in an increased response to the released neurotransmitter. This phenomenon is due to an increased sensitivity of the receptors and not due to an increase in production or release of neurotransmitters or growth of axon branches. Polarization of the membrane at rest is a normal physiological process and not directly related to denervation supersensitivity.
