Anerve poison that blocked neurotransmitter receptors on the dendrites would inactivate the enzyme that degrades the neurotransmitter cause continued stimulation of the membrane of the receiving neuron inhibit the regeneration of the neurotransmitter for use by the sending neuron prevent reception of a signal in a receiving neuron

The correct answer is: prevent reception of a signal in a receiving neuron

Neurotransmitters are signal molecules or chemical messengers which transmit signals across a chemical synapse. Neurotransmitters send the signal, from one neuron (nerve cell) to another neuron, from neuron to muscle cell (motor plate), or from neuron to gland cell.

Drugs that bind to neurotransmitter’s receptor can have two effects on its action:

•Antagonists-they bind to receptor and thus prevent a neurotransmitter from binding to it

•Agonists-they bind to receptor and mimic the normal neurotransmitter (have the same effect as neurotransmitter).
