the vertebral arch
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 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.
Filtration Slits. They allow water, glucose, vitamins, amino acids, small plamsa proteins, ammonia, urea, and ions to pass.
vertebrae Inter means "between", vertebral obviously means vertebrae as mentioned above, and foramina is plural for foramen, which is a hole. Intervertebral foramina are formed in the space between two vertebrae. When two or more vertebral bones are stacked, the intervertebral foramina would be inferior to the pedicles of the superior vertebrae and superior to the pedicles of the inferior vertebrae. It will create a hole that goes between the two vertebrae horizontally. The spinal cord goes through the vertebral foramen vertically, and the nerve roots slip out horizontally through the intervertebral foramina.
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.
