What Is the Vertebral Body?
The vertebral body is the main part of the vertebrae's weight-bearing. It is short cylindrical, full of cancellous inside, dense [1] on the surface, thinner, and the top and bottom are rough. It connects with the adjacent vertebra by intervertebral fibrocartilage. The back of the vertebral body is slightly depressed, and together with the vertebral arch surrounds the foramen verte foramen. Each foramen penetrates and forms a spine canal that houses the spinal cord.

- The vertebral body is the main part of the vertebrae's weight-bearing. It is short cylindrical, full of cancellous inside, dense [1] on the surface, thinner, and the top and bottom are rough. It connects with the adjacent vertebra by intervertebral fibrocartilage. The back of the vertebral body is slightly depressed, and together with the vertebral arch surrounds the foramen verte foramen. Each foramen penetrates and forms a spine canal that houses the spinal cord.
- The vertebral body is divided into heteroconcave vertebral body, biconcave cone, anterior concave vertebral body, posterior concave vertebral body and flat concave vertebral body.
- Double-concave vertebral body : The two ends of the vertebral body are concave. It is the most primitive vertebral body in vertebrates. It is found in fishes, caudate, apodips, some caudal, and beak head lizards.
- Anterior-concave vertebrae : Anteriorly-convex vertebrae, found in most tailless, pterosaurs, true crocodiles, and lizards.
- Concave vertebral body : The vertebral body is lordosis and lordosis. It is found in the part of the tailless, cervical vertebrae of some dinosaurs and the anterior vertebrae of sauropods. Hetero-concave vertebrae: The articular surface between the cervical vertebrae is saddle-shaped, and the intervertebral joints are extremely mobile, which is unique to birds, and is also called saddle-shaped vertebrae.
- Biplanar vertebral body : The vertebral body joints are wide and flat, the contact surface is wide, and the intervertebral discs with cartilage between the vertebral bodies are separated. They are found in mammals.
- In addition, there are concave vertebrae and staggered vertebrae , which are found in some tailless classes.
