False ribs

Definition

False ribs are the five lower ribs (8th to 12th) that do not directly attach to the sternum but either connect indirectly via cartilage or not at all. The false ribs include both the floating ribs (11th and 12th) which have no anterior attachment, and the ribs (8th to 10th) that connect to the cartilage of the rib above.
