Vertebrae are the highly specialized bones which collectively make up the spinal column. The spinal column is such a distinctive anatomical feature that all animals with spinal columns are known as vertebrates, referencing the vertebrae. In humans, 33 separate bones make up the spinal column, and the structure begins to form around the third week of gestation.
The human vertebral column is the vertebral column (backbone or spine) of the human skeleton, consisting of 24 articulating vertebrae and 9 fused vertebrae in the sacrum and the coccyx. The vertebrae in the column are separated from each other by intervertebral discs.he vertebral column consists of vertebrae. The vertebrae of the cervical, thoraic and lumbar spines are independent bones, and generally quite similar. The vertebrae of the sacrum and coccyx are usually fused and unable to move independently.
