Interchondral articulations
Encyclopedia
Interchondral Articulations (articulations of the cartilages of the ribs with each other).—The contiguous borders of the sixth, seventh, and eighth, and sometimes those of the ninth and tenth, costal cartilages
articulate with each other by small, smooth, oblong facets.
Each articulation is enclosed in a thin articular capsule, lined by synovial membrane and strengthened laterally and medially by ligamentous fibers (interchondral ligaments) which pass from one cartilage to the other.
Sometimes the fifth costal cartilages, more rarely the ninth and tenth, articulate by their lower borders with the adjoining cartilages by small oval facets; more frequently the connection is by a few ligamentous fibers.
Costal cartilages
The costal cartilages are bars of hyaline cartilage which serve to prolong the ribs forward and contribute very materially to the elasticity of the walls of the thorax.-Differences from 1-12:...
