Definition

White matter is a component of the central nervous system primarily made up of myelinated nerve fibers. It facilitates communication between different brain regions and the spinal cord.

5 Must Know Facts For Your Next Test

1. White matter integrity is crucial for efficient neural signaling and cognitive functions.
2. Nutritional deficiencies, such as lack of vitamin B12, can lead to white matter damage.
3. Healthy fats, particularly omega-3 fatty acids, support the maintenance and repair of white matter.
4. Aging is associated with a decline in white matter volume, which can impact neurological wellness.
5. Consuming antioxidants helps protect white matter from oxidative stress and inflammation.
