Yes, sort of. In MS patients, leukocytes have crossed the blood-brain barrier and have entered into the central nervous system. There they attack the oligodendrocytes and the myelin sheaths they have produced to protect nerve axons. This can directly cause damage to the nerve or it can leave the nerve unprotected. Also, it greatly slows down the action potential in affected neurons, inhibiting nerve functioning in inflicted areas.
Multiple sclerosis affects the central nervous system in the brain and spinal column by hardening the material (myelin) that insulates and protects the nerves. Once the insulation is destroyed, the nerve can no longer transmit signals properly, much like an electrical wire that has been shorted.
c) destruction of the myelin sheath
MS is short for Multiple Sclerosis. Its an auto immune disease that attacks the brain and spinal cord.
An autoimmune disease is one in which the immune system mistakenly attacks the host which it is protecting. In Multiple Sclerosis, the immune system attacks and destroys the myelin sheath surrounding nerve fibers, leaving behind hard plaques or scars (called scleroses, thus "multiple sclerosis" meaning "many scars").
Multiple sclerosis
are you asking 'what is the chronic inflammatory disease in which the immune system attacks the myelin sheath of nerve cell axions? if that is your question, the answer is Multiple Sclerosis.
It is neither bacterial nor viral. Multiple sclerosis is an autoimmune disease. That means that your body's immune system is attacking parts of your body. In the case of multiple sclerosis the immune system is attacking the protective cover around the nerve cells.
The onset of MS is usually at age 20 to 40 years
Multiple sclerosis means "many scars." This name comes from the pathology of the disease, where nerve cells are attacked by the immune system. T-cells will destroy the myelin sheath surrounding nerve cells, leaving hard, plaque-like regions called scleroses.
Multiple Sclerosis is thought by some scientists to be an autoimmune disease, but some disagree. Crohn's disease used to be described as an autoimmune disease, but more recent reseach has revealed it to be an immune deficiency state. Trigger Finger is also not an autoimmune disease.
Multiple Sclerosis effects the myeline sheath of the spinal cord
HIV destroys the body's immune system while multiple sclerosis causes the immune system to become less efficient
When the immune system attacks part of the body, rather than foreign organisms or substances, that is called an auto-immune disease. The disease of multiple sclerosis (M/S) is caused by this; the immune system attacks the myelin sheath of nerve cells. Myelin is a type of fat, needed to insulate nerve axons so that nerve messages can be transmitted successfully.
multiple sclerosis may be the body's delayed immune reaction to viruses such as measles, Herpes simplex, rubella, and parainfluenza.
