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

Learning activity II ch 8-U4 Exercise 1: Anthony Figueroa is a CPA‚ who works for an accounting consulting firm. His annual salary income is $70‚000. Anthony is considering opening up his own consulting firm. He estimates that the annual rent for an office would cost him $20‚000; a secretary would cost $24‚000 per year. If he would rent office equipment‚ he would have to pay $11‚000 per year. The purchase of required supplies‚ payment of electricity bills‚ water and telephone bills‚ would cost

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

Short Responses for Garrison CH 8 and CH 9‚ Midterm‚ and part of AICE CH 7 Explain how wind‚ temperature‚ density‚ the Coriolis effect and the shape of the sea bed produce ocean currents and upwelling. Ocean currents are the continuous movement of ocean water driven by forces acting on the water‚ including: wind‚ waves‚ the Coriolis effect‚ temperature‚ salinity and tides. The contours of the sea bed influence the strength and direction of the current. Surface ocean currents are generally
