AP Success - AP Biology Conceptual Analysis: Info Storage & Transfer - Nervous

Myelin is a fatty substance that insulates the axons of many neurons, allowing for faster transmission of electrical signals. Multiple sclerosis (MS) is a disease where the body's immune system mistakenly attacks the myelin sheath, leading to a variety of neurological symptoms.

Describe the process of myelination and its importance in the functioning of the nervous system.

In the context of MS, explain how the destruction of the myelin sheath affects the transmission of electrical signals in neurons.

Predict the potential effects on a person's motor skills and sensory perception if the myelin sheath of neurons in the brain and spinal cord is progressively damaged.

A claim is made that early detection and treatment of MS can slow the progression of the disease and improve quality of life. Justify this claim using your understanding of the nervous system and the role of myelin.
