You’re working as a research assistant in Dr. Maricel’s lab and have been asked to measure the electrical activity of neurons. What voltage would you see if you were correctly measuring the resting potential?

After the peak of the action potential, potassium ions leave the axon. Why?

When the neuron is at resting potential, what happens at the sodium channels?

What feature do epinephrine, norepinephrine, and dopamine have in common?

Exams are open-notes but must be my own notes, not resources from other sources.

____ tolerance occurs because less drug gets to the target site.

Do you agree to us an electronic signature (typed name) for this document?

Nicole meets the criteria for substance abuse disorder due to her abuse of opiates. Because the receptors that opiate drugs bind to are found in the ___, an overdose may result in suppressed breathing and heart rate.

Dr. Avery administers a drug that blocks sodium channels in the neuronal membrane. What effect will this have on the neuron?

Researchers have developed a new drug that is a dopamine agonist. Explain the ways this drug could affect each step of synaptic activity. Be sure to include the following terms/concepts with definitions/explanations: synthesis, storage, release, receptors, reuptake, and enzymatic degradation. NOTE: You won’t earn credit by just typing the information from class word-for-word. Your job is to convince me that you understand it, and the only way to do that is by using your own explanation. Make sure you explain each term/phrase above; don’t just use them in a sentence. Using bullet points instead of complete sentences is fine so long as all the necessary information is provided.
