Question

A new drug is developed that prevents the demyelination occurring in the progress of multiple sclerosis. The drug protects the cells responsible for the synthesis

and maintenance of myelin in the central nervous system. These cells are most likely which of the following?
A- Microglial cell
B-oligodendrocyte
C- ependymal cell
D- astrocyte

Answer 1

B-oligodendrocyte.

Answer 2

B - oligodendrocyte.

Step-by-step explanation:

Oligodendrocytes are cells that produce myelin, a fatty substance that insulates nerve fibers and allows them to transmit nerve impulses quickly and efficiently. Myelin is essential for the proper functioning of the nervous system.

Multiple sclerosis (MS) is a disease that affects the central nervous system (CNS). In MS, the body's immune system attacks myelin, causing damage to the nerve fibers. This damage can lead to a variety of symptoms, including fatigue, weakness, numbness, and vision problems.

There is no cure for MS, but there are treatments that can help to manage the symptoms. The new drug that you described protects oligodendrocytes from damage, which helps to prevent the demyelination that occurs in MS. This can help to improve the symptoms of MS and slow the progression of the disease.

Microglial cells are immune cells that are found in the CNS. They play a role in inflammation and in the removal of damaged cells. Ependymal cells are cells that line the ventricles of the brain and the central canal of the spinal cord. They produce cerebrospinal fluid and help to regulate its flow. Astrocytes are star-shaped cells that are found throughout the CNS. They play a role in supporting and protecting neurons.
