3. Compare and contrast an action potential and a local post-synaptic potential in terms of where they occur on a neuron, the change in charge, how they propagate through a neuron. (3) 6. What is an EPSP and IPSP? Provide a definition, not just spelling out the acronym. (2) Provide a specific example of how each can be generated in a neuron. (4) 8. Imagine humans have a single hypothetical neuron that controls the decision to get out of bed....

Compare and contrast cardiac and skeletal muscle in terms of electrical stimulus and action potentials (excitation-contraction coupling), role of calcium, energy use and production, and ways to develop increased force of contraction. How does the vulnerability of the myocardium relate to the fact that heart disease is the leading cause of death?

Compare and contrast a grade potential with an action potential?

Explain how graded potentials and action potentials are different. On which part of a neuron would you expect a graded potential to occur? An action potential? Explain what an EPSP and IPSP are? How would you generate an IPSP?

Compare and Contrast the Neuronal Action Potential vs Cardiac Action Potential. Focus on the steps of the both action potentials and identify the difference(s). What is the significance and involvement of Calcium ions in the cardiac action potentials? Why are Calcium ions not necessary in the neuronal action potentials, but are essential in the myocardial AP?

Compare and Contrast the Neuronal Action Potential vs Cardiac Action Potential. Focus on the STEPS (depolorization, refractory period repolorization, Na/K pumps, resting membrane potential, ect...) of the both action potentials and identify the difference(s). What is the significance and involvement of Calcium ions in the cardiac action potentials? Why are Calcium ions not necessary in the neuronal action potentials, but are essential in the myocardial AP?

1)Compare and contrast synaptic potentials and action potentials. How each of these encode stimulus strength. 2)Describe in detail how one messenger can trigger the release of another second messenger. 3)On a molecular level, what absolutely refractory period? Can another action potentials be fired during this period? What principle of AP firing is due to the absolute refractory period?
