Hereditary neuropathies are diseases of the peripheral nerves that are genetically passed from parent to child. The most common of these is Charcot-Marie-Tooth disease type 1. It is characterized by weakness in the legs and, to a lesser degree, the arms -- symptoms that usually appear between mid-childhood and age 30.
1 Chlorine ions are colored yellow in the VRML model. 2  Sodium (Na +) and potassium (K +) are positive ions. 3  They are found on both sides of the membrane. 4  Na + ions are in greater concentration outside the neuron whereas K + ions are more concentrated inside the neuron. 5  Na + ions are colored pink in the VRML model.
1. I do not understand why the cell, while at resting potential, is negative on the inside relative to the outside of the cell. Potassium and sodium both have positive charges so why is the inside negative? Is it because there is more sodium and potassium outside the cell than inside? I read this sentence in my book and it confused me, it said During resting potential, the number of negative charges on the inside of the cell equals the number of positive on the outside. Once again why do they call the charges on the inside negative?
