In this STEAM project, I chose to draw nerves, one being normal, and the other affected by multiple sclerosis. Multiple Sclerosis (MS) is an autoimmune disease that attacks the myelin sheath of neurons, particularly of the central nervous system (CNS). MS can disrupt communication between the CNS and the body. Causes are unknown. Effects can range depending on part of the CNS affected. There is no cure for MS but a person with MS can use medicine such as therapeutic agents to relieve symptoms.
