What is a floating rib?

A floating rib, also known as a false rib or vertebral rib, is a rib that does not connect directly to the sternum like the rest of the ribs. Instead, it is attached only to the thoracic vertebrae in the back. Most people have 12 pairs of ribs, with the first 7 pairs being true ribs that connect to the sternum directly, and the last 5 pairs being false ribs, including the floating rib.

Floating ribs are often more flexible than true ribs because they are not attached to the sternum, allowing for greater movement and flexibility in the chest area. They also provide less protection to the organs in the abdominal cavity compared to true ribs. Floating ribs are more vulnerable to injury due to their position and lack of direct connection to the sternum.

Overall, floating ribs play a role in protecting the organs in the abdominal cavity and providing structure and support to the chest area.
