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

Australia has regional and global links with other countries for aid. This report will describe the advantages and disadvantages for Australia that result from its Indonesian aid links which includes improving Australia’s reputation and providing employment and training opportunities for people. However country may become too dependent on other countries for support and dishonest leaders may use the money for their own benefits. First and foremost‚ Australia is popularly known to be ‘champions of

How does this trace compare to the trace that was generated with the unheated glass bar? The tracing were similar but the heat increase the action potential 3. What explanation can you provide for this? The heat stimuli generated a stronger nerve impulse Activity 4: Chemical Stimulation 1. Does the sodium chloride generate an action potential? Yes 2. Does this tracing differ from the original threshold stimulus tracing? If so‚ how? No‚ they are the same. 3. Does the hydrochloric acid generate

CHAPTER 1 Basic principles of pacing Malcolm Kirk The aim of this chapter is to give sufficient background and information about cardiac pacemakers to allow interpretation of electrocardiograms (ECGs) and telemetry strips of normal pacemaker behavior. For more in-depth information‚ such as would be necessary for programming pacemakers‚ a standard pacing text should be consulted. Several of these are listed in the bibliography. Most italicized terms are defined in the glossary at the end of the chapter
