Neurophysiology of Nerve Impulses ACTIVITY 1 The Resting Membrane Potential 1. Explain why increasing extracellular K+ reduces the net diffusion of K+ out of the neuron through the K+ leak channels. If the extracellular K+ increases then the concentration of intracellular K+ will decrease causing a decrease in the steepness of the concentration gradient and fewer K+ ions would be drawn out. 2. Explain why increasing extracellular K+ causes the membrane potential to change to a less negative

ACTIVITY 1: THE RESTING MEMBRANE POTENTIAL 1. Explain why increasing extracellular K+ reduces the net diffusion of K+ out the neuron through the K+ leak channels? When the diffusion is greater on one side‚ the other side will slow down. 2. Explain why increasing extracellular K+ causes the membrane potential to change to a less negative value. How well did the results compare with your predictions? There are two potassium’s for every sodium so the increase of potassium will make it more

PET 3351 Exercise Physiology Second Exam Review (Fall 2012) Chapter IV: The Physiological Basis of Muscular Strength and Flexibility 1. Strength is operationally defined as the maximal force that can be exerted in a single effort. Using this definition‚ strength should be assessed using one repetition maximum (1 RM)‚ though we often estimate strength using tests that may involve multiple repetitions. 2. In strength training and rehabilitation‚ emphasis should be given to both the concentric
