The pedicles and laminae of a vertebra form the vertebral arch, which encases and protects the spinal cord. The pedicles are short, thick projections that extend backward from the vertebral body, while the laminae are flat plates that connect the pedicles to the spinous process. Together, they create an opening called the vertebral foramen, through which the spinal cord passes. This structure is essential for maintaining the integrity and function of the vertebral column.

What superior articular process of the sacrum articulate?

What do the pedicles laminae and spinous processes form?
The pedicles, laminae, and spinous processes form the vertebral arch of a vertebra. Together, they create a protective structure that surrounds the spinal cord and contributes to the overall stability and support of the vertebral column. The pedicles connect the vertebral body to the laminae, while the spinous processes extend posteriorly, providing attachment points for muscles and ligaments. This configuration allows for flexibility and movement while safeguarding the central nervous system.

the vertebral arch
What structures make up the vertebral arch?
The pedicles, laminae and the intervertebral foramina form the vertebral arch.
What form the sides of the vertebral arch?

The form laminae is the plural form; the singular form is lamina.
How many articulations are in the spinal vertebra?
There are four: one joint with the vertebra that is superior and one with the vertebra which is inferior plus superior and inferior processes (2) come off the pedicles. These articulate with the articular processes of the vertebrae above and below.
What is the plural form of lamina papyracea?
