Question

Give the step which occurs prior to the movement of action potential down the axon of a neuron.

• A. Neurotransmitters bind to receptors on the dendrite of the neuron.
• B. Neurotransmitters are released from the axon terminals of the neuron.
• C. The action potential travels through the synapse from a nearby neuron.
• D. Vesicles in the axon terminal release their contents at the synapse.
• E. The cell body releases neurotransmitters down the length of the axon.

Answer 1

The correct option is A Neurotransmitters bind to receptors on the dendrite of the neuron.

• At a synapse, one neuron sends a message to a target neuron—another cell.
• At a chemical synapse, an action potential triggers the presynaptic neuron to release neurotransmitters.
• These molecules bind to receptors on the postsynaptic cell and make it more or less likely to fire an action potential. Hence, the step which occurs prior to the movement of an action potential down the axon of a neuron is Neurotransmitters bind to receptors on the dendrite of the neuron.
So, the correct answer is 'Neurotransmitters bind to receptors on the dendrite of the neuron'.
