She is discharged from the hospital and schedules a follow up appointment with the neurologist.

When she returns to the neurologist, they discuss Kathy’s different options for treatment. Because there is no cure for the disease, options in medication vary greatly. She decides to try daily injections of Copaxone, a medication that is similar in structure to a protein found in myelin.

Kathy continues to see the neurologist on a regular basis and gives herself an injection every evening. Over the course of seven months of therapy, she only experiences one occurrence of numbness, which subsides after a couple of days. She tries to stay positive and tries to minimize the disease’s impact on her life.

7. What is myelin and how does it affect the transmission of nerve impulses? Identify the cells responsible for the formation of myelin. Myelin is the substance that forms a medullary sheath around the axis cylinder of some nerve fibers. The myelin acts as a strong electrical conductor. Schwann cells are responsible for the formation of myelin.
