articulations of bony thorax

costochondral union/junction

- Between costal cartilage and ribs (where the cartilage and bone are bound together - Ribs 1-10 - Synarthrodial; no movement

sternoclavicular joint

-Articulation between the clavicle and the sternum -synovial joint -Gliding-Plane motion Diathrodial joint

costovertebral joint

-Diarthrodial -synovial joint between rib head and vertebra -articulates with the head of the rib and vertebral body

sternocostal joint

-Synovial joint between rib cartilage and sternal edge except 1st rib -between rib 2-7 -synovial joint -plane (gliding motion) -diathrodial

sternocostal joint of rib 1

-between the sternum and ribs of rib 1 -cartilage of the rib attaches directly to the manubrium with no synovial capsule -cartilaginous joint -synchondrosis type -no movement

costotransverse joint (posterior articulation)

-joints between the ribs and vertebral column -plane (gliding) -Synovial -Diathrodial -articulate with the tubercle of the rib and transverse process

interchondral joints

continuous border between the costal cartilage of the anterior 6-9th rib -synovial joint -gliding (plane) motion *interchondral joints between the 9th-10th cartilages are not synovial --> classified as fibrous syndesmosis
