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.
Neuron Resting Potential-Resting Membrane Potential of the neuron. The voltage difference between the intracellular space and the extracellular space when a neuron is in its non-activated state, is the cells resting potential, which is around -- 70 mV. The resting potential is the electrical charge the cell has when it is resting and when it is not stimulated by any open ion channels.
