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.
The hog-nosed skunk (Conepatus leucontus) has a long snout that is hairless for about 1 inch (2.5 cm) at the top. It is 26 inches (66 cm) long and weighs 4 pounds (1.8 kg). Its entire back and tail are white and the lower sides and belly are black.
