Compare and contrast the neuronal action potential vs cardiac action potential. Focus in the steps of the both action potentials and identify the difference. What is the significance and involvement

Compare and contrast the neuronal action potential vs cardiac action potential. Focus in the steps of the both action potentials and identify the difference.  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 essential in the myocardial AP?  […]
