Hey JedKampe, There are numerous drugs and conditions that can cause a false positive for cocaine not to mention human error. Substances that can cause a false positive drug test result: Amoxicillin is an antibiotic in the penicillin group of drugs. It fights bacteria in your body. Ampicillin is another antibiotic similar to amoxicillin.
When the nerve is damaged,the action potential remains between the electrodes and doesn't reach the second electrode (i.e potential difference remains positive and doesn't go into negative phase) , the biphasic action potential changes into monophasic action potential i.e with single phase. Source(s):E: biphasic action potential change into the monophasic action? Why does the biphasic action potential change into the monophasic action potential after nerve injury between the two recording electrodes?
Best Answer: An action potential is an electrical signal that travels from one part of a nerve cell to another. The action potential begins at the soma or cell body. It then travels down the axon (this might be as long as 1 meter in some cases). At the nerve terminal (the end of the axon), the action potential stops. But, it triggers a chemical signal (neurotransmitter) to be released across the synapse (the gap between two nerve cells or a nerve cell and a muscle cell).
