Document Summary

Baker | fors 3331 | spring 2017 | lecture 13 | page 1. A cage of cartilage and bone attached posteriorly to the vertebral column. Serves to protect organs like the heart and lung. Ribs 1-10 ossify from 4 centers: the epiphysis for the head and articular and non-articular parts of the tubercle appear in the teens, the epiphyses fuse to the rib body in early adulthood. Ribs 1-10 articulate posteriorly with the thoracic vertebrae. Rib length increases from rib 1-7 then decreases from 7-12. The head of most ribs articulates with vertebra of its own number and with the vertebra immediately superior i. e. the 7th rib attaches to the superior costal facet of t7 and to the inferior costal facet of t6. Ribs 1, 11, and 12 typically articulate with their own vertebra. The tubercles of ribs attach to the transverse process of its own number.
