The three main parts of a vertebra are the vertebral body, the vertebral arch, and the processes.
Here's a breakdown of each part:
-
Vertebral Body: This is the large, drum-shaped, weight-bearing portion of the vertebra located at the front. It's designed to withstand compression and support the weight of the body.
-
Vertebral Arch: This arch-shaped structure extends from the posterior aspect of the vertebral body and encloses the vertebral foramen, creating a protective bony passageway for the spinal cord.
-
Processes: These are bony projections that extend from the vertebral arch. They serve as attachment points for muscles and ligaments, providing leverage and stability to the spine. These include the spinous process (projects posteriorly), transverse processes (project laterally), and articular processes (superior and inferior, which allow vertebrae to articulate with each other).
In summary, these three components work together to provide structure, protection, and support for the spinal column.
