- AKA shaft, begins at angle, curves anteriorly

4

the head and tubercle of the rib connect to what facets?

where are these facets?

4, costovertebral articular facet and 10, costotransverse articular facet

- on the vertebral body and transverse process, resepectively

rib overview

- 12 pairs total

- 7 pairs "true" ribs that connect to  the sternum via their own cartilages

- 5 pairs "false" ribs attach indirectly (or not at all)

- 2 pairs "floating" ribs don't attach to sternum at all
