Pre-lab Quiz Results
You scored 100% by answering 5 out of 5 questions correctly. 1 The
end of the axon where it contacts a target is called the
You correctly answered: axon terminal.
2 Neurotransmitter is released into the synaptic gap by
You correctly answered: exocytosis.
3 Exocytosis of neurotransmitter from the axon terminal is triggered by an increase in the intracellular
concentration of
You correctly answered: Ca2+.
4 Neurotransmitter released into the synaptic gap reaches the target cell by
You correctly answered: diffusion.
5 At the target, neurotransmitter
You correctly answered: does all of the above.
Experiment Results
Predict Questions
1 Predict Question 1: You have just observed that each action potential in a burst can trigger additional
neurotransmitter release. If calcium ions are removed from the extracellular solution, what will
happen to neurotransmitter release at the axon terminal?
Your answer: There will be less neurotransmitter release.
2 Predict Question 2: What will happen to neurotransmitter release when low amounts of calcium are
added back to the extracellular solution?
Your answer: Neurotransmitter release will increase a small amount.
3 Predict Question 3: What will happen to neurotransmitter release when magnesium is added to the
extracellular solution?
