The exact location of the vertebral body is where the intervertebral fibrocartilage meets the neighboring vertebrae. The vertebral body is the main weight-bearing part of the vertebrae, and the surface of the cortex is thin and rough both above and below. Depending on where they are located, they are mainly categorized as cervical, thoracic, and lumbar vertebrae. The cervical vertebrae are called cervical vertebrae and have 7 vertebrae, small bodies, triangular foramina, short spinous processes, and a hole in the center of the transverse process. The position in the chest, called the thoracic vertebrae, has 12 blocks, with larger vertebrae than the cervical vertebrae and smaller than the lumbar vertebrae. The vertebral foramina are smaller and heart-shaped. In the lumbar region, called lumbar vertebrae, there are 5 blocks, the vertebrae are tall, high in the front and low in the back, and kidney-shaped. The vertebral foramina are large and triangular in shape. Vertebral body is the most important part of the entire spinal vertebrae, mainly play the role of load-bearing, for the approximate cylindrical, two ends and around the bone dense, full of bone inside the cancellous, play a cushioning shock and reduce the role of weight. The upper and lower parts of the vertebral body are the main weight-bearing parts, and the surface is rough, which is conducive to the force of the intervertebral disc. The middle of the vertebral body is connected to the spinous process by the arch, and the back of the vertebral body and the arch together form the spinal canal to accommodate the spinal cord.
