Description
The body (shaft) of first rib is the long, curved part of the bone that extends from its neck to its costal end. It is flattened in appearance, however, because of its orientation, it differs from the other ribs by having superior and inferior surfaces and external and internal borders. The body of first rib consists of a scalene tubercle and grooves for the subclavian artery and vein. Unlike the other ribs, the first rib does not have a costal groove and lacks a distinct angle of rib, although it does provide attachment sites for the intercostal muscles.
