The action potential of a nerve cell is all-or-nothing whereas synaptic transmission is graded. Explain what this means.
What is the difference between an agonist and an antagonist?
What is the limbic system? Name at least three of its component parts.
How does the myelin sheath help speed neural transmission?
Raccoons have much more precise control of their paws than dogs do. Explain how you would expect the primary motor cortex of racoons to differ from a dog's primary motor cortex?
In class, we discussed an example of an amputee (right arm) that started feeling sensation in his phantom limb whenever he was shavingthe left side of his face. Explain how this is possible.
Name three mechanisms by which damaged nerves can regain lost function. For one of the three you listed, briefly explain the mechanism by which this occurs.
