The vertebral body is the large, cylindrical part of a vertebra, which is a bone in the spine. It serves as the main weight-bearing structure, providing support and stability to the spinal column. Each vertebral body is separated by intervertebral discs, which act as cushions to absorb shock and allow for movement. Vertebral bodies are found in different regions of the spine, including the cervical, thoracic, and lumbar areas. They vary in size and shape, with lumbar vertebrae being the largest to support more weight. The vertebral bodies also protect the spinal cord, which runs through the vertebral foramen.
