Each of the vertebra in the spine is considered an irregular bone, but when it comes to their size, it will vary based on factors including but not limited to where it is located in the vertebral column and posture. In order to deal with a person’s mobility and any stress placed upon the spine, the vertebra may change. Let’s briefly explore the intricate structure of the vertebra.
Each vertebra has a body which is comprised of a middle portion known as the centrum and a posterior area called the vertebral arch. This body is made up of a type of bone which is often referred to as spongy bone because of its resemblance to a sponge. This bone is covered by another type of bone called cortical bone, which creates a thin protective layer and is capable of withstanding torsion or bending. The body of the vertebra also has rough, flattened upper and lower surfaces. These surfaces are called endplates and they allow the attachment of the intervertebral discs which are responsible for holding the vertebra together, allowing them to move slightly while also absorbing significant shock.
