Body
The ribs are attached posteriorly to the thoracic vertebrae of the spine through their articulation with the costal facets located on the bodies and transverse processes of the vertebrae. This connection allows for rib movement during breathing and provides structural support for the rib cage.
they are attached by cartilage formed between the actual rib and the back bone
One side of the pubis articulates interiorly with the other side of the pubis, joining at the pubic symphysis. Posteriorly it articulates with the sacrum, the Acetabulum proximally articulates with Femur bone. So therefore there are three articulation points for the pelvic girdle.
The temporal bones articulate with the parietal bones superiorly, the sphenoid bone anteriorly, the occipital bone posteriorly, and the zygomatic bones laterally.
The surface that articulates with the ribs which is simply called the the "Demi-Facet" for the head of the rib. There is also a part on the transverse process of the thoracic vertebrae which acts as a block to prevent the rib from moving posteriorly.

The second rib is classified as an atypical rib because it does not follow the typical rib anatomy pattern. It has a longer and more curved body compared to other ribs, with a prominent angle where it articulates with the sternum. These differences make the second rib distinct from the other ribs in the rib cage.
