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.

A baby antler is called a "pedicle." When young male deer, known as bucks, grow their antlers, they begin as pedicles, which are growth structures on their skulls. As the season progresses, these pedicles develop into antlers, which are shed and regrown annually.
The fusion of pedicles and lamina in the vertebral column forms the vertebral arch. This structure helps protect the spinal cord and provides attachment points for muscles and ligaments that support the spine.
The pedicles, laminae and the intervertebral foramina form the vertebral arch.
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 presence of five nonrib-bearing lumbar vertebrae with intact pedicles indicates that these vertebrae are part of the lower back (lumbar region) of the spine and are structurally sound. Nonrib-bearing means they do not have ribs attached, which is typical for lumbar vertebrae. Intact pedicles suggest that there are no fractures or deformities in these supporting structures, contributing to the overall stability of the vertebral column. This condition is generally favorable for spinal health and function.
The sides of the vertebral arch are formed by the pedicles and laminae, which extend from the vertebral body to enclose the spinal cord within the spinal canal. These structures provide protection and support for the spinal cord and nerves.
Reactive bone marrow is a polyclonal bone marrow response meaning that the bone marrow is overproducing one or more cell types as part of the immune response. Edema is swelling caused by the overproduction of cells. Pedicles are part of the vertebrae that make up the spine, the part which connects the body and spinous process. L means lumbar and bilaterally means both sides so it means that the reactive bone marrow edema is occurring in both pedicles of the vertebrae.
Polyps are small tumors growing on a stalk.
