How do neurons work? Choose the answer choice with the correct order of steps: The action potential propagates a signal down the axon; then dendrites receive external stimuli, and finally at the synapse, neurons interact with other cells by sending neurotransmitters. Dendrites receive the external stimuli, the action potential propagates a signal down the axon, and then, at the synapse, neurons interact with other cells by sending neurotransmitters. The action potential propagates a signal down the axon; then, at the synapse, neurons interact with other cells by sending neurotransmitters, and finally Dendrites receive external stimuli.

When action potentials arrive at a synapse between a neuron and another cell, they stimulate the release of molecules of a _____ that diffuse over to that cell.
A neurotransmitter is released into synapses when O levels of that neurotransmitter fall below threshold. O sufficient dendrites are activated. O an action potential reaches the end of the axon. • glial cells trigger release.

When neurotransmitters cross the synaptic cleft and bind to ligand-gated potassium channels, the inside of the cell becomes more positive. As a result, the cell approaches threshold and an inhibitory postsynaptic potential is generated. Subsequently, the axon hillock generates an action potential.
