The connection between the ribs and the vertebrae is facilitated by the costovertebral and costotransverse joints. Each rib articulates with the thoracic vertebrae at two points: the head of the rib connects to the bodies of two adjacent vertebrae, while the tubercle of the rib attaches to the transverse process of the corresponding vertebra. This structure allows for the flexibility and movement of the ribcage during respiration while providing stability to the thoracic spine.
thoracic vertebrae
The thoracic vertebrae are found in the chest region of the body. Humans have twelve thoracic vertebrae which are located between the cervical and lumbar vertebrae.
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
the back bone is the vertebrae
The variation in number is in the tail, where cattle can have between 18 to 20 vertebrae in the caudal region, or the tail. There are also seven cervical (neck) vertebrae, 13 thoracic (rib cage) vertebrae, six lumbar (loin) and five sacral (sirloin) vertebrae.
The ribs are the bones located in the posterior thorax between the second and seventh vertebrae. These ribs articulate with the thoracic vertebrae in the back and form the rib cage that helps protect vital organs in the chest cavity.
An articulation between a vertebrae and a rib
Rib pair 7, also known as the true ribs, articulates directly with the sternum via its costal cartilage and has a typical articulation with the thoracic vertebrae at the facets on the bodies and transverse processes of T7. In contrast, rib pair 10 is considered a false rib because it does not attach directly to the sternum but instead connects to the costal cartilage of rib 9. This leads to differences in their articulations; rib 10 typically has a more variable articulation with T10, which may not include a full facet for the rib head due to its atypical connection. Overall, the structural differences reflect their functional roles in the rib cage.

Non-rib bearing lumbar type vertebral bodies refer to the specific structure of lumbar vertebrae in the lower back, which do not have rib attachments. Unlike thoracic vertebrae that possess facets for rib articulation, lumbar vertebrae are characterized by their larger, more robust bodies designed to support greater weight and provide stability. This structural adaptation facilitates mobility and load-bearing, crucial for bipedal locomotion.
