The vast majority of humans have 24 ribs, arranged in 12 pairs.
Understanding Human Ribs
Based on anatomical data, the standard number of ribs in humans is quite consistent across the population.
According to the reference:
- The vast majority of people are born with 12 pairs of ribs.
- This results in a total of 24 ribs.
- This number is generally the same no matter their sex.
Variations in Rib Count
While 24 is the typical number, exceptions can occur. These are usually due to specific genetic factors present at birth.
- Supernumerary Ribs: Some individuals are born with more than 24 ribs. These extra ribs are often called supernumerary ribs.
- Agenesis of Ribs: Conversely, some people are born with fewer than 24 ribs, a condition known as agenesis of ribs.
These variations, having either too many or too few ribs, are considered anomalies from the standard anatomy.
In summary, the widely accepted number of ribs for the vast majority of people is 24, forming 12 pairs, though genetic factors can lead to individual differences.
