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.
A. Sodium and potassium ions in higher on the inside of its membrane. B. Sodium and potassium ions is higher on the outside of its membrane. C. Sodium ions are higher on the inside, potassium ions are higher on the outside. D. Sodium ions are higher on the outside, potassium ions higher on the inside.
