Exercise 3: Neurophysiology of Nerve Impulses Worksheet Eliciting a Nerve Impulse Activity 1: Electrical Stimulation 1. Do you see any kind of response on the oscilloscope screen? No there was no response‚ the line was flat 2. What was the threshold voltage‚ or the voltage at which you first saw an action potential? 3.0V 3. How does this tracing compare to the one that was generated at the threshold voltage? At 3.5V the high & low peaks were just slightly above and below respectively

and Relaxation of skeletal muscles surrounding the veins 7 WHY ARE THE WALLS OF ARTERIES PROPERTIONATELY THICKER THAN THOSE OF THE CORRESPONDING VEINS? Because the blood is pumped directly into arteries so there is more pressure on the arteries 8 THE ARTERIAL SYSTEM HAS ONE OF THESE; THE VENOUS SYSTEM HAS TWO BRACHIOCEPHALIC 9 THESE ARTERIES SUPPLY THE MYOCARDIUM CORONARY 10 TWO PAIRED ARTERIES SERVING THE BRAIN EXTERNAL CAROTID‚ INTERNAL CAROTID 11 LONGEST VEIN IN THE LOWER LIMB
