Describe the electrical and chemical communication within and between neurons
What will be an ideal response?
Answer: A good answer should include the following key points.
? Stimulating a neuron past its threshold causes an electrical impulse, called an action potential, to travel down the axon from the cell body to the axon terminal.
? Action potential causes the release of chemical neurotransmitters from the axon terminal.
? The neurotransmitter travels across the synaptic cleft and binds to receptor sites on the receiving neuron.
? The neurotransmitter can cause either an excitatory effect or an inhibitory effect in the receiving neuron, making it more likely or less likely it will fire an action potential, respectively.
