Which of the following causes the release of neurotransmitter molecules?
A) the reception of a signal from the postsynaptic neuron
B) an electrical signal reaching the end of the cell body
C) an electrical signal reaching the terminal bouton
D) an electrical signal reaching the beginning of the dendrite

Question

Quizplus · Accepted Answer

When an electrical signal reaches the terminal bouton at the end of the axon, it triggers the release of neurotransmitter molecules into the synaptic cleft, which then bind with receptors on the postsynaptic neuron to transmit the signal. The other options (A, B, and D) do not trigger the release of neurotransmitter molecules.
