GENERAL HISTOLOGY

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: -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-3: -The average person is born with 33 individual bones (the vertebrae) that interact and connect with each other through flexible joints called facets. By the time a person becomes an adult most have only 24 vertebrae because some vertebrae at the bottom end of the spine fuse together during normal growth and development.

Detailed explanation-4: -Technically speaking, the spinal column includes 34 bones. Twenty-four bones are articulated vertebrae bones (a singular bone is a vertebra). At the bottom of the spinal column are the remaining bones, the naturally fused vertebrae of the sacrum and coccyx, which join with your pelvis (hip bones).
