COSTOVERTEBRAL ARTICULATIONS The articulations of the heads of the ribs {articulationes capitu-lorum) are of the ginglymoid variety of diarthrosis.

The ventral portion ofthe capsule is reinforced by three radiating bundles of fibers calledthe radiate ligaments of the head {lig. capituli costce radiatum).These start at the head; the middle one is attached to the inter-vertebral disc and the others to the vertebral bodies. The intraarticular ligament {lig. capituli costce intraarticulare) iswithin the joint; it is attached to the ridge on the head, between thetwo facets, and to the intervertebral disc.
