Costochondral joint

The costochondral joints are the articulations between the false ribs and costal cartilage. They are hyaline cartilagenous joints. Each rib has a depression shaped like a cup that the costal cartilage articulates with. There is normally no movement at these joints. Joints between costal cartilages of ribs 6-9 are plane synovial joints. Articulation between costal cartilage of rib 9 and rib 10 is fibrous.
