  • Development of the sternum
    • Sternal bars (pair of ventral mesenchymal bands) develop ventrolateral on the body wall
    • Chondrofication occurs as the bars move medially
    • Fuse by week 10 craniocaudally in the median plane
    • Form cartilaginous models of the manubrium, sternebrae, and xiphoid process
    • Manubrium develops from mesenchyme btw the clavicle and neural crest contributions in the region of endochondral ossification
    • Ossification occurs craniocaudally before birth except for the xiphoid process which may never completely ossify
  • Congenital anomalies associated with the development of the sternum
    • Pectus excavatum
    • Pectus carinatum
    • Cleft sternum
    • Cervical Ectopia Cordis
    • Thoracic Ectopia Cordis
    • Thoracoabdominal Ectopia Cordis
  • Congenital anomalies associated with the development of the vertebral column
    • Klippel-Feil Syndrome (Brevicollis)
    • Spina bifida
    • Accessory ribs and Fused ribs
    • Hemivertebrae
    • Rachischisis (Cleft Vertebral Column)
