U2: Thoracic Cage

Thoracic Cage

QuestionAnswer
Thoracic Cage or Bony Thorax includes sternum, ribs, and costal cartilages
Sternum flat bone to which 10 of 12 pairs of ribs attach via costal cartilages; parts are manubrium, body, and xiphoid process
Manubrium superior portion of sternum; medial end of clavicles articulate with it, has suprasternal/jugular notch
Body middle and largest portion of sternum
Xiphoid process inferior tip portion of sternum; usually blue on models b/c made of hyaline cartilage
Ribs 12 pairs; all articulate posteriorly with thoracic vertebrae
First 7 pairs of ribs true ribs which attach directly to sternum via costal cartilages
Last 5 pairs of ribs (pairs 8-12) false ribs
Rib pairs 8-10 false ribs whose costal cartilages do not exten all the way to the sternum, but join the cartilages associated with more superior ribs; have only indirect attachment to the sternum
Rib pairs 11-12 false ribs that are more specifically designated as “floating” ribs b/c have no costal cartilages and no attachment to sternum
Intercostal spaces space between ribs and costal cartilages that are filled with breathing-related skeletal muscles named external intercostals (asstd. w/ inhalation/inspiration) and internal intercostals (asstd. w/exhalation/expiration)
