Study Notes
Costal Demifacets of Thoracic Vertebrae
- Located on the lateral aspects of thoracic vertebrae.
- Each thoracic vertebra has two costal demifacets for articulation with ribs.
- Allows for stability and movement of the thoracic cage.
Superior Costal Demifacet
- Found on the upper part of each thoracic vertebra.
- Articulates with the head of the rib that pairs with that vertebra.
- Typically, ribs 1-10 utilize superior demifacets for proper attachment.
Inferior Costal Demifacet
- Located on the lower part of each thoracic vertebra.
- Works in conjunction with the superior facette of the adjacent vertebra.
- Important for connecting the lower ribs (typically ribs 2-11) to the spine for rib cage stabilization.
Transverse Process with Costal Facets of Thoracic Vertebrae
- Extends laterally from each thoracic vertebra.
- Contains costal facets which connect to the tubercle of the rib.
- Key role in rib articulation points, enhancing the thoracic spine’s structural integrity and mobility.
