ABSTRACT

The third to tenth ribs can be regarded as typical. The head of the ribs have two facets. The larger, lower facet articulates with its own vertebral body. The smaller, upper facet articulates with the immediately superior vertebral body. The tubercle situated at the lower aspect of the neck of the rib articulates with its own vertebral body’s transverse process. At the anatomical angle of the rib, the immediately posterior aspect of the bone is bent medially toward the vertebral body.
