What Would a Nerve Poison That Blocked Neurotransmitter Receptors on the Dendrites

Question

What would a nerve poison that blocked neurotransmitter receptors on the dendrites do?
A) It would cause continued stimulation of the membrane of the receiving neuron.
B) It would prevent transmission across the synaptic cleft.
C) It would inhibit the regeneration of neurotransmitter for use by the synaptic knobs.
D) It would inactivate the enzyme that degrades the neurotransmitter.

Accepted Answer

Blocking neurotransmitter receptors on the dendrites would prevent transmission across the synaptic cleft, as the neurotransmitter would not be able to bind to the receptors on the receiving neuron's membrane. This would result in a lack of communication between the neurons, leading to a range of symptoms depending on which neurotransmitter and brain regions are affected.
