How many vertebral bodies are there? What letter is used to represent it?

There are 32 vertebrae in the human body, the cervical vertebra is represented by "C", the thoracic vertebra by "T", the lumbar vertebra by "L" and the sacral vertebra by "S".

Vertebral body is the main bearing part of vertebral body, which is short and cylindrical, full of sponginess, thin surface density and rough upper and lower surfaces, and connected with adjacent vertebral bodies through intervertebral fibrocartilage. The posterior part of the vertebral body is slightly concave, which forms vertebral foramen together with the vertebral arch. Each vertebral foramen penetrates to form a spinal canal for accommodating the spinal cord.

Extended data

Vertebral points are morphologically divided into the following types:

1, biconcave vertebral body: The two ends of the vertebral body are concave, which is the most primitive vertebral body in vertebrates, and is found in fishes, cauda, Anpoda, partially tailless and coracoid sauropods.

2. Anterior concave vertebral body: The vertebral body is concave and convex, which is found in most tailless animals, pterosaurs, true crocodiles and lizards.

3. Vertebral depression: the vertebral body is convex and concave, which is found in the tailless cervical vertebrae of some dinosaurs and the anterior vertebrae recommended by sauropods.

4. Abnormal vertebral body: The articular surface between cervical vertebrae is saddle-shaped, and the intervertebral joints are extremely active, which is unique to birds, also known as saddle-shaped vertebral body.

5. Biplanar vertebral bodies: Vertebral joints are wide and flat, with a wide contact surface, and intervertebral discs with cartilage are separated between the vertebral bodies, which is found in mammals.
