A resting cell is negative due to more sodium ions outside the cell than potassium ions inside the cell. The negativity is due to the membrane being more permeable to potassium ion movement than sodium ion movement.
The function of myelin sheaths is to insulate nerve axons so that electrical impulses are quicker. They are found on nerve axons.
An inactivated sodium ion channel is a channel that is blocked by something other than the normal closing of the channel. A closed sodium channel is just a channel that is closed by a normal mechanism.
