PhysioEx 9.0 Exercise 3 Neurophysiology of Nerve Impulses A C T I V I T Y 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 potassium reduces the concentration gradient‚ and less potassium diffuses out of the neuron and into the cell. 2. Explain why increasing extracellular K_ causes the membrane potential to change to a less negative value.

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

Birth Defetc s No one is immune to birth defetc s‚ yet not everyone is equally susceptible. Birth defetc s are not merely a medical problem. They have profound effetc s on the social and psychological well being of their family and friends. In the normal course of fetal development‚ cells migrate to their appropriate destination so that organs and limbs form where they should. Usually‚ the genes perform flawlessly‚ but mistakes can and do occur. Some of the most common birth defetc s
