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.
Pedicles and laminae of a vertebra form the?
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.
Which vertebra does not have a spinous process?
Cervical vertebrae have a bifurcated spinous process.
Which vertebrae don't have a spinous process?
C-1 (Atlas)
When you palpate a spine what bone do you feel?
You are feeling the spinous process of your vertebrae.
What structure is associated with the bifid tips of the cervical vertebrae?
Spinous process
What is the vertebral type with a forked spinous process?
In the cervical spine, the C2-C6 vertebrae generally have bifid spinous proceses.
What are two accessory processes of the lumbar vertebrae?
the transverse process and the articular process also spinous process
What is the The pointed projection that extends posteriorly from the fused lamina of vertebrae?
spinous process
What part of the vertebrae provide levers against which muscles pull?
spinous process and transverse process
What is Reactive bone marrow edema within the L5 pedicles bilaterally mean?
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.
What are the main parts of the vertebrae called?
The body of each vertebra is attached to a bony ring consisting of several parts. A bony projection on either side of the vertebral body called the pedicle supports the arch that protects the spinal canal. The laminae are the parts of the vertebrae that form the back of the bony arch that surrounds and covers the spinal canal. There is a transverse process on either side of the arch where some of the muscles of the spinal column attach to the vertebrae. The spinous process is the bony portion of the vertebral body that can be felt as a series of bumps in the center of a person's neck and back.
