Question

Quizplus · Accepted Answer

The shape of the neurotransmitter must fit the receptor site on the postsynaptic neuron in order to affect it. The other answer choices are not correct because dendrites and axon terminals are part of the neuron's structure, and synaptic vesicles are the packets that release neurotransmitters into the synapse. The cell body is also not directly involved in the signaling process.
