Consider a myelinated axon having Em of -80 mV. Threshold to elicit an action potential is -40 mV. An action potential (100 mV amplitude, measured from Em to peak) arrives at the first node of Ranvier. Local current flowing ahead of the spike reaches the second node, the distance being x = 0.25A. Calculate the magnitude of the depolarization caused by local current reaching the second node using the equation: V = Voe A. 45 mV B. 78 mV C.65 mV D. 100 mv

A typical pacemaker delivers 60 electrically stimulating pulses per minute to a heart, where each 3.5 volt pulse lasts 0.4 milliseconds. The resistance of the heart tissue between the pacemaker electrodes is typically about 600 ohms. If the pacemaker's battery pack stores about 18 kilojoules of chemical energy (the equivalent of about 2 AA batteries) and converts its energy to electrical energy in the heart tissue with an efficiency of 35%, about how long will the battery pack last?

In a certain article, laser therapy was discussed as a useful alternative to drugs in pain management of chronically ill patients. To measure pain threshold, a machine was used that delivered low-voltage direct current to different parts of the body (wrist, neck, and back). The machine measured current in milliamperes (mA). The pretreatment experimental group in the study had an average threshold of pain (pain was first detectable) at ? = 3.19 mA with standard deviation ? = 1.03 mA. Assume that the distribution of threshold pain, measured in milliamperes, is symmetric and more or less mound-shaped. (Round your answers to two decimal places.) (a) Use the empirical rule to estimate a range of milliamperes centered about the mean in which about 68% of the experimental group will have a threshold of painfrom mA to mA(b) Use the empirical rule to estimate a range of milliamperes centered about the mean in which about 95% of the experimental group will have a threshold of painfrom mA to…
