Typical ribs
3 to 9
The lower large facet of head of rib articulates with
Numerically corresponding vertebra
Upper small facet of head of rib articulates with
Next Higher vertebra
Neck of rib lies at
Transverse process of its own rib
Tubercle of rib has facets
Medial articular facets = costotransverse joint and lateral non articular facets
Costal groove contains
Posterior intercostal vessels and intercostal nerve
Shortest, broadest and most curved rib
First rib
First rib
Has no costal groove, shaft is not twisted
The upper surface of the shaft is crossed obliquely by two shallow grooves separated by a ridge. The ridge is enlarged at the inner border of the rib to form the scalene tubercle (Fig. 13.7a).
When the rib is placed on a horizontal plane, i.e. with the superior surface facing upwards, both the ends of the rib touch the surface
