ANATOMY

Detailed explanation-1: -The bones of the backbone are known as vertebrae. The back is composed of twenty-four individual bones called vertebrae that are stacked one on top of the other to make up your backbone or spinal column. The 24 separate vertebrae are interspaced with cartilage and then additionally, the sacrum and coccyx are present.

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: -vertebral column, also called spinal column, spine, or backbone, in vertebrate animals, the flexible column extending from neck to tail, made of a series of bones, the vertebrae.

Detailed explanation-4: -Vertebrae: The spine has 33 stacked vertebrae (small bones) that form the spinal canal. The spinal canal is a tunnel that houses the spinal cord and nerves, protecting them from injury. Most vertebrae move to allow for a range of motion. The lowest vertebrae (sacrum and coccyx) are fused together and don’t move.

Detailed explanation-5: -The facet joints link the vertebrae together and give them the flexibility to move against each other. Each vertebra has a hole in the center, so when they stack on top of each other they form a hollow tube that holds and protects the entire spinal cord and its nerve roots.
