What best describes the arrangement of the 12 costae?
The 12 costae, or ribs, are arranged in pairs on either side of the thoracic vertebrae, forming a symmetrical structure that protects the thoracic cavity and supports the chest wall. They are categorized into three types: the first seven pairs are true ribs, directly attached to the sternum; the next three pairs are false ribs, which connect to the sternum via cartilage; and the last two pairs are floating ribs, which do not attach to the sternum at all. This arrangement allows for flexibility and expansion of the thoracic cavity during breathing.
What are the names of the ribs that don't connect to the sternum?
The ribs that don't connect to the sternum are known as floating ribs. There are two pairs of floating ribs, specifically the 11th and 12th pairs of ribs. Unlike true ribs, which attach directly to the sternum, and false ribs, which are indirectly connected, floating ribs are only attached to the vertebrae in the back and do not have any anterior connection. This anatomical feature provides flexibility and protection to the lower back.
