Detailed explanation-1: -Although they’re very light, bones are strong enough to support our entire weight. Bones also protect the body’s organs. The skull protects the brain and forms the shape of the face. The spinal cord, a pathway for messages between the brain and the body, is protected by the backbone, or spinal column.

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). Your vertebrae stack on top of each other, from your pelvic bones to your skull.

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).

Detailed explanation-4: -Protects and supports organs: Your skull shields your brain, your ribs protect your heart and lungs, and your backbone protects your spine. Stores minerals: Bones hold your body’s supply of minerals like calcium and vitamin D.

Detailed explanation-5: -Meninges, bones, discs, ligaments, and muscles protect the spinal cord.
