A postsynaptic neuron has an RMP of -70mV and a typical threshold of -55mV. It has three presynaptic inputs-from neurons X, Y, and Z. Stimulation of neuron X causes the postsynaptic neuron to depolarize by 0.5 mV. When X and Y are stimulated simultaneously, the postsynaptic neuron depolarizes by 1 mV. If X fires 10 times and Y fires 10 times the result will be
A. threshold is reached and an AP is fired. B. the membrane depolarizes. C. many APs are fired. D. presynaptic inhibition. E. a subthreshold summation.

On a normal ECG, a wave for repolarization of the atria is not recorded. Why?
a. The leads are not placed in a position to pick it up. b. No repolarization of the atria occurs normally. c. It occurs simultaneously with ventricular depolarization and is masked by the QRS complex. d. It does not travel through body fluids. e. It is too small to be picked up by external recording electrodes.
