Physiology University of Phoenix SCI/230 7/5/2013 Instructor Nancie Harris There are currently 33 diverse species of dolphin that exist in lakes (freshwater) and oceans (saltwater) of the world. Each species of dolphin‚ whether marine or river‚ has an anatomy which allows them to thrive in certain conditions. The anatomy of the dolphin has been enhanced throughout the years in order for them to continue to adjust to their domain. This paper will break down the adaptions in the anatomy of one

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
