ANATOMY

Detailed explanation-1: -Key parts of your spine include vertebrae (bones), disks, nerves and the spinal cord. The spine supports your body and helps you walk, twist and move.

Detailed explanation-2: -The vertebrae (back bones) of the spine include the cervical spine (C1-C7), thoracic spine (T1-T12), lumbar spine (L1-L5), sacral spine (S1-S5), and the tailbone. Each vertebra is separated by a disc. The vertebrae surround and protect the spinal cord.

Detailed explanation-3: -Vertebrae. Vertebrae are the 33 individual bones that interlock with each other to form the spinal column.

Detailed explanation-4: -Bones are fastened to other bones by long, fibrous straps called ligaments (LIG-uh-mentz). Cartilage (KAR-tul-ij), a flexible, rubbery substance in our joints, supports bones and protects them where they rub against each other.

Detailed explanation-5: -The spine is our body’s central support structure. It keeps us upright and connects the different parts of our skeleton to each other: our head, chest, pelvis, shoulders, arms and legs. Although the spine is made up of a chain of bones, it is flexible due to elastic ligaments and spinal disks.
