How important is the diaphragm?

  • It does 75-85% of the work of breathing and covers the inferior thoracic aperture, costal, sternal, and vertebral portions

  • Manubrium- suprasternal notch, clavicular notch, notch for costal cartilage of 1st rib
  • Body-sternal angle (louis) called manubriosternal joint, articular facets to costal cartilage of ribs 3-6
  • Xiphoid process-ossifies at about 15-30 years of age, costal cartilage of the 7th rib
300
  • Where do the anterior intercostal arteries arise from?
  • 1-6 arise from the internal thoracic artery
