1 Multiple sclerosis (MS) is a disease that causes demyelination (disruption of the myelin that insulates and protects nerve cells) of spinal nerve and brain cells.  Although the exact case is unknown, multiple sclerosis is considered to be an autoimmune disease.
The skunk is not a rodent. They belong to the family Mephitidae and the order Carnivora which does not include rodentia. They are sometimes placed in the family Mustelidae (weasels) but have been discovered to be less related than was thought.
Other species of skunks, such as the spotted skunk and the hog-nosed skunk, can be found further south, ranging from Canada to Central and South America. Stink badgers, which resemble the hog-nosed skunk, are strictly found in the Philippines, Malaysia, and Indonesia.
