Articulation of head of rib

The Articulations of the Heads of the Ribs (costocentral articulations) constitute a series of gliding or arthrodial joints, and are formed by the articulation of the heads of the typical ribs with the facets on the contiguous margins of the bodies of the thoracic vertebræ and with the intervertebral fibrocartilages between them; the first, tenth, eleventh, and twelfth ribs each articulate with a single vertebra.

The ligaments of the joints are:


 * Articular capsule
 * Radiate ligament
 * Interarticular ligament
