Verified step by step guidance

Begin by understanding the anatomy of the human rib cage. The rib cage is part of the axial skeleton and consists of ribs, thoracic vertebrae, and the sternum.

Identify the number of ribs in a typical human. Humans normally have 12 pairs of ribs, making a total of 24 ribs.

Differentiate between true ribs, false ribs, and floating ribs. True ribs are the first seven pairs that attach directly to the sternum. False ribs are the next three pairs that attach to the sternum indirectly via cartilage. Floating ribs are the last two pairs that do not attach to the sternum at all.

Consider the statement given in the problem: 'A human normally has ten pairs of ribs.' Compare this statement with the anatomical fact that humans have 12 pairs of ribs.

Conclude that the statement is false based on the anatomical evidence that humans have 12 pairs of ribs, not ten.
