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?
The action potential is the brief electrical impulse that is responsible for the propagation of information down the axon of a neuron. Some important concepts involved with the action potential are the membrane potential, resting potential, threshold.hen the membrane potential reaches its peak, the action potential is attained, and the sodium channels become refractory and no more sodium ions enter the cell. Potassium ions continue to leave the cell, and the membrane potential slowly decreases towards the resting potential.
