ANATOMY

Detailed explanation-1: -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-2: -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.

Detailed explanation-3: -The backbone protects the spinal cord.

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

Detailed explanation-5: -The backbone is also called the vertebral column. The main function of the vertebral column is the protection of the spinal cord. It also provides stiffening for the body and attachment for the pectoral and pelvic girdles and many muscles.
