Session 9: The Nervous System - Assignment #2 PhysioEx Assignment : Exercise 3 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. Increasing the extracellular K+ causes the membrane potential to change to a less negative value because when K+ ions diffuse out across the membrane they are leaving behind a net negative charge. 2. Explain

Activities and Learning Exercises Ch 3 Instructions for Task Analysis Assignment Your job is to formulate a training objective and write a task analysis of a skill; for example‚ how to eat a sandwich cookie. Remember this is an example‚ but you should assume that your trainees are familiar with what a sandwich cookie is. Your job is to teach them how to go about eating one or can they really eat just one? First‚ compose a goal statement/learning objective for your training. Next‚ complete your

Individual Exercise 3 (10 points) 1. A shoe manufacturer’s data show that the distribution of shoe size is normal with a mean of 11inches and SD 1.5 inches. * A manger of the company claims that 70% of the times shoe size will be between 8 and 12 inches. What do you think? In your deliverables‚ write a few lines about what you think of the manager’s claim and what would you advise him to do. (1 point) * How would you modify the manager’s claim if the distribution of shoe size was not

results compare with your prediction? Your answer: If extracellular K+ is increased then the intracellular K+ will decrease. Fewer intracellular K+ ions would result in the membrane potential being less negative. This is what I predicted to happen. 3. Explain why a change in extracellular Na+ did not significantly alter the membrane potential in the resting neuron? Your answer: There are less sodium leak channels than potassium leak channels‚ and more of the potassium channels are open. 4. Discuss
