Components of Vertebrae
The components of a typical vertebra are the posterior neural arch, also known as the vertebral arch, and the vertebral body, which consists of a massive anterior centrum. The body’s rough, flattened surfaces—both upper and lower—make it simple for the intervertebral discs to connect to them. The pedicles and laminae make up the vertebral arch. Each side of the body has two pedicles that connect to form the arch. The lamina, which runs from each pedicle to the middle and back, completes the vertebral arch.
The vertebra gives rise to seven processes, which are projections from tissues:
- The four articular processes
- A single spinous procedure
- There are two transverse processes.
Vertebrae – Bones, Diagram and Features
Vertebrae are a collection of bones which are found in all vertebrate animals. We have intervertebral discs that connect the 33 different-sized bones that make up our spinal column. Lumbar (5), sacral (1-fused), coccygeal (1-fused), cervical (7), and thoracic (12) are the five regions that make up the spinal column.
These 33 bones make up the region where the human cranium ends, and the coccyx begins in this group. The vertebrae provide structural support and protection to the spinal cord and enable flexibility and movement of the spine, allowing for various body motions.
