A)always involves acetylcholine.
B)always involves some neurotransmitter that stimulates the next neuron.
C)is a simple continuous "domino" flow of negativity or ions from the axon to the next dendrite.
D)involves either an inhibitory or stimulating neurotransmitter chemical.
E)All of the choices are correct.

Question

Quizplus · Accepted Answer

The event at the chemical synapse involves either an inhibitory or stimulating neurotransmitter chemical. While acetylcholine is a common neurotransmitter at some synapses, not all synapses use it, so choice A is incorrect. Choice B is also incorrect because some neurotransmitters can inhibit the next neuron rather than stimulate it. Choice C is not accurate as the flow of ions between neurons is not continuous, but rather a rapid response to the release of neurotransmitters. Therefore, the correct answer is D - the event at the chemical synapse involves either an inhibitory or stimulating neurotransmitter chemical.
