No significant differences between the noise-exposed pigs and controls were observed for rate of feed utilization; rate of weight gain, or food intake, nor was there injury or anatomical change to the organ of Corti of the inner ear. Heart rate of a large number of weaned pigs was measured before, during, and after sound exposure Bond et al.

Neurophysiology of Nerve Impulses: The end of the axon where it contacts a target is called the You correctly answered: Neurotransmitter is released into the synaptic gap by You correctly answered: Exocytosis of neurotransmitter from the axon terminal is triggered by an increase in the intracellular concentration of You correctly answered: Neurotransmitter released into the synaptic gap reaches the target cell by You correctly answered: At the target, neurotransmitter You correctly answered: Experiment Results Predict Question: 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? There will be less neurotransmitter release. What will happen to neurotransmitter release when low amounts of calcium are added back to the extracellular solution?

Neurotransmitter release will increase a small amount. What will happen to neurotransmitter release when magnesium is added to the extracellular solution? There will be no neurotransmitter release. Why does the stimulus intensity affect the amount of neurotransmitter release at the axon terminal?

Both a and b are correct.

Please send results to:

Why is there no neurotransmitter release from the axon terminal when there are no calcium ions in the extracellular solution? Exocytosis of the synaptic vesicles is calcium dependent.

How is the neurotransmitter stored in the axon terminal before it is released? Comparing the low intensity stimulus to the high intensity stimulus, the high intensity stimulus causes You correctly answered: Increasing stimulus intensity makes more number of synaptic vesicles be released.
