Articular Facet of Tubercle of Seventh Rib

Description

The articular facet is the smooth, oval area found along the tubercle of the seventh rib. It articulates with the transverse costal facet of the seventh thoracic vertebra, forming the seventh costotransverse joint.

Overall, these articular facets on tubercles are only present on the first to tenth ribs, while the eleventh and twelfth ribs lack this bony feature.
