The ribs articulate with the thoracic vertebrae. The thoracic vertebrae also articulate with each other.
The ribs articulate with the thoracic vertebrae.
The cervical and lumbar vertebrae do not articulate with the ribs. The thoracic vertebrae are the only ones that articulate with the ribs.

thoracic vertebrae :)
At the thoracic vertebrae, joints include the intervertebral joints between the individual vertebrae, the costovertebral joints where the ribs articulate with the vertebrae, and the costotransverse joints where the ribs articulate with the transverse processes of the thoracic vertebrae.
There are 12 pairs of ribs that articulate with the thoracic vertebrae, one per vertebra. The upper 7 pairs of ribs articulate directly with the sternum, either via their own costal cartilage or the cartilage of the rib above. Ribs 8-10 articulate indirectly with the sternum through a shared cartilage, while ribs 11 and 12 are floating ribs that do not connect to the sternum.
The thoracic facets and demifacets articulate with the ribs, which form joints known as costovertebral joints. The facets on the thoracic vertebrae articulate with the heads of the ribs, while the demifacets articulate with the necks of the ribs.
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.
The two locations on a thoracic vertebra where the ribs articulate are the costal facets on the sides of the vertebral body and the transverse costal facets on the transverse processes. These articulations form the joints that connect the ribs to the thoracic vertebrae.
Floating ribs (ribs 11 and 12) do not articulate with the sternum directly but are attached only to the thoracic vertebrae in the back. They are considered "floating" because they lack an attachment to the sternum or cartilage.
