ANATOMY

Detailed explanation-1: -Both the brain and the spinal cord are protected by bone: the brain by the bones of the skull, and the spinal cord by vertebrae, a set of ring-shaped bones. They’re both cushioned by layers of membranes (called meninges) and cerebrospinal fluid.

Detailed explanation-2: -A protective layer of bone called the vertebral column covers and protects your spinal cord. The bones in the vertebral column are called vertebrae (plural of one spine bone, a vertebra).

Detailed explanation-3: -The dura mater or pachymeninx is made up of two layers of whitish membrane. The outer layer (endosteal) is called the periosteum. An inner layer (meningeal), lines the inside of the entire skull and creates little folds or compartments in which parts of the brain are protected and secured.

Detailed explanation-4: -Meninges, bones, discs, ligaments, and muscles protect the spinal cord.
