Vertebra

In the vertebrate spinal column, each vertebra forms a unique, irregular bone with an intricate structure consisting of both bone and hyaline cartilage. The proportions of these components fluctuate depending on the specific segment of the backbone and the species of vertebrate animal in question. At its core, a vertebra's basic configuration consists of two primary elements: the body, which is the largest part, and the centrum, situated centrally.
