Final answer:
The statement is false for the human rib cage, which has seven true ribs that directly attach to the sternum, comprising the top seven pairs of the total 12 pairs of ribs.
Step-by-step explanation:
The statement 'The primal lamb rack contains seven rib bones' as it pertains to the human rib cage is false. The human rib cage consists of 12 pairs of ribs, and the top seven pairs are classified as true ribs. These true ribs are directly attached to the sternum via their costal cartilage.
The primal lamb rack, referring to a cut of meat, may have a varying number of ribs, but in the context of human anatomy, the number of true ribs is seven on each side, not including the false or floating ribs.
The ribs are divided into three groups:
- True ribs (1-7) attach directly to the sternum.
- False ribs (8-10) are connected to the ribs above them.
- Floating ribs (11-12) do not connect to the sternum at all.
Each rib consists of bone and is flattened and curved, with the costal cartilage extending to meet the sternum in the case of true ribs.
