Study Notes
Structures of a Typical Vertebra
- Body: The anterior mass that provides strength and support to the vertebra.
- Pedicle: Posterior projections extending from the body that help form the vertebral arch.
- Lamina: Plates that connect the transverse processes to the spinous process; crucial for the structural integrity of the vertebra.
- Vertebral Arch: Formed by the fusion of the pedicles and lamina, encasing the vertebral foramen.
- Transverse Process: Lateral projections found at the junction of the pedicle and lamina; serve as muscle attachment points.
- Spinous Process: A single posterior projection extending from the vertebral arch; important for muscle attachment and overall structure.
- Vertebral Foramen: Opening between the body and vertebral arch that allows for the passage of the spinal cord.
- Articular Processes: Composed of two superior and two inferior projections; allow for articulation with adjacent vertebrae, crucial for spinal movement.
- Articular Facets: Flat surfaces on each articular process; superior facets face posteriorly, while inferior facets face anteriorly, facilitating articulation with neighboring vertebrae.
Key Anatomical Directions
- Posterior: Refers to the back side of the vertebra; important for defining various projections and structures in relation to the spine.
- Anterior: Refers to the front side of the vertebra; crucial in understanding the orientation of the vertebral body.
