One of the main physiological changes that occur within the cardiovascular system in response to exercise is heart rate. When engaging in exercise‚ the amount of energy required increases instantaneously within the skeletal muscles. This sudden demand creates increasing stress on the cardio-respiratory system to remove the waste products and carbon dioxide from the cells and provide more oxygen for the working cells. This surge of extra energy that is needed requires the heart to pump faster and

Review Sheet Exercise 3 Neurophysiology of Nerve Impulses Eliciting (Generating) a Nerve Impulse 1. Why don’t the terms depolarization and action potential mean the same thing? They require different things. Action potential requires depolarization and repolarization. Depolarization doesn’t require anything. 2. What was the threshold voltage in Activity 1? 3.0V 3. What was the effect of increasing the voltage? How does this change correlate to changes in the nerve? The action potential
