Quick Summary

An opisthocoelous vertebra is a type of vertebra characterized by its shape. The anterior (front) end of the centrum is flat or convex, while the posterior (back) end is concave, meaning it is hollowed out. This specific structure is a defining feature of this particular type of vertebra.1

Vertebrae are fundamental components of the vertebral column, which evolved from the notochord. Each vertebra typically consists of a centrum and a neural arch that encloses the spinal cord.2
