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.
These are about the size of a tree squirrel and are the smallest skunks except for the pygmy spotted skunk (S. pygmaea), which can fit in a personâs hand. The hog-nosed skunks (genus Conepatus) of North America can be larger than striped skunks, but those of Chile and Argentina are smaller.
