The human spine is made up of 24 vertebrae, seven cervical (neck), 12 thoracic (upper back) and five lumbar (lower back) vertebrae.
The photo shows the vertebrae of a one year-old on the left, and those of a six year-old on the right. In a one year-old each vertebra consists of three pieces of bone which are connected by cartilage.
The picture on the left shows where in the body these bones are located.
