The 11th and 12th ribs are classified as floating ribs, meaning they do not attach to the sternum or have a direct connection to the rib cage. Unlike the true ribs, which connect to the sternum via costal cartilages, these floating ribs have only a posterior attachment to the vertebrae and end in the muscle of the abdominal wall. This anatomical feature allows for greater mobility and flexibility in the lower thoracic area, providing protection to the underlying organs while accommodating respiratory movements.
The four ribs at the bottom of the rib cage are called floating ribs because they are not directly attached to the sternum. They are known as ribs 11 and 12, with rib 11 being the first of the floating ribs and rib 12 being the last.
Costochondritis, also known as Tzietze's syndrome, is inflammation of the rib and joint.
The joint connecting the sternum and the first rib is a cartilaginous joint known as the sternocostal joint. This joint provides flexibility and allows for movements during breathing.

Yes
The 1st rib articulates primarily with the first thoracic vertebra at the costovertebral joint. Additionally, it forms a joint with the manubrium of the sternum at the sternocostal joint. This rib is unique in its anatomy and plays a critical role in the thoracic structure and function.
The junction of the rib and cartilage is the costochondral joint.
An articulation between a vertebrae and a rib
The Rendevous It's wonderful!
No, it is between the clavicle and manubrium
