PATHOLOGY

Detailed explanation-1: -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). Your vertebrae stack on top of each other, from your pelvic bones to your skull.

Detailed explanation-2: -Note: The brain is enclosed and protected by the skull which forms the head in vertebrate organisms. And the skull is made up of the cranium and the mandible.

Detailed explanation-3: -Cerebrospinal fluid (CSF) surrounds the spinal cord, which is also shielded by three protective layers called the meninges (dura, arachnoid and pia mater). The spinal cord lies inside the spinal column, which is made up of 33 bones called vertebrae.
