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?
Resting Potential Resting potential refers to the polarization of cellular fluid within a neuron that provides the potential to produce an action. Let's use a sports example - in baseball, the batter standing at home plate waiting for the pitcher to throw the ball may be standing still (appears to be in a resting state), but is actually prepared to respond to the pitch. You might say the batter has resting potential to swing the bat.
