Humans typically have 24 ribs in total, arranged in 12 pairs, with 12 ribs on each side of the body
. These ribs form the rib cage, which protects vital organs such as the heart and lungs. The ribs are categorized as follows:
- True ribs (1–7 pairs): These ribs attach directly to the sternum via costal cartilage.
- False ribs (8–10 pairs): These do not connect directly to the sternum but are connected to the cartilage of the rib above.
- Floating ribs (11–12 pairs): These ribs do not connect to the sternum at all and are only attached to the vertebrae at the back
There is no difference in the number of ribs between males and females; both typically have the same 24 ribs, debunking the myth that men have fewer ribs than women
. Some people may have variations such as extra ribs (supernumerary ribs) or fewer ribs due to genetic anomalies, but these cases are rare
. In summary, the standard human rib count is:
- 12 pairs of ribs
- Total of 24 ribs
This consistent anatomy supports the protection and flexibility required for breathing and organ safety.
