What is the Most Precise Description of a False Rib

Question

What is the most precise description of a false rib?
A)A rib that does not articulate with the vertebral column
B)A rib that never ossifies, but remains as cartilage throughout life
C)A rib that connects directly to the sternum by its own costal cartilage
D)A rib that connects indirectly to the sternum by a costal cartilage, or has no connection to the sternum
E)A rib that has no cartilaginous connection to the sternum

Accepted Answer

A false rib is a rib that connects indirectly to the sternum by a costal cartilage or has no connection to the sternum. This is in contrast to true ribs (ribs 1-7), which each have their own separate costal cartilage that connects directly to the sternum, and floating ribs (ribs 11-12), which have no connection to the sternum at all. The term "false" in this context simply means "not directly attached."
