Spinal Anatomy Including Transverse Process And Lamina

The pedicles which are short thick bilateral processes that protrude posteriorly from the posterolateral corner of the vertebral body forming the lateral walls.

Anatomy of the vertebral body. The vertebral arch is posterior meaning it faces the back of a person. The vertebral body is the largest part of the spinal bone and it comprises the anterior portion of the vertebra meaning it is located in the front relative to the bony ring that attaches in the back. The vertebral column originally develops as a series of 33 vertebrae but this number is eventually reduced to 24 vertebrae plus the sacrum and coccyx.

Vertebral body is the thick oval segment of bone forming the front of the vertebra also called the centrum. A cylinder of bone known as the vertebral body makes up the majority of the lumbar vertebraes mass and bears most of the bodys weight. The arch surrounds the hollow vertebral foramen and connects the body to the bony processes on the posterior of the vertebra.

Together these enclose the vertebral foramen which contains the spinal cord. Anatomy of a vertebra a typical vertebra consists of two parts. The vertebral column is curved with two primary curvatures thoracic and sacrococcygeal curves and two secondary curvatures cervical and lumbar curves.

Posteriorly the body is connected to a thin ring of bone known as the arch. Vertebrae articulate with each other to give strength and flexibility to the spinal column and the shape at their back and front aspects determines the range of movement. The body of the vertebra and the vertebral arch form the vertebral foramen the larger central opening that accommodates the spinal canal which encloses and protects the spinal cord.

The laminae are bilateral flattened plates that extend posteromedially from the posterior margin of the pedicles. The cavity of the vertebral body consists of cancellous bone tissue and is encircled by a protective layer of compact bone. The vertebral body and the vertebral arch.
