What 3 things protect the brain and spinal cord?
The brain and spinal cord are covered by three layers of meninges, or protective coverings: the dura mater, the arachnoid mater, and the pia mater. Cerebrospinal fluid surrounds the brain, cushioning it and providing shock absorption to prevent damage.
