How Many Ribs Does Man And Woman Have?

Our rib cage and ribs are great illustrations of just how fascinating the human body anatomy is. They’re strong enough to support the skeleton and shield important organs like the heart, lungs, and spleen from the elements in the chest cavity.

How Many Ribs Does A Woman And Man Have?

Regardless of gender, the vast majority of people have 12 sets of 24 ribs. Some people are born with an abnormally large or small number of ribs. These issues don’t always necessitate treatment. In many cases, your doctor will advise you to wait and watch.

People born with unique genetic anomalies are an exception to this rule. These might be excessive ribs (supernumerary ribs) or insufficient ribs (agenesis of ribs). On the other hand, the ribs and rib cage are flexible enough to expand and contract with the breath as the lungs fill and empty.

How Many Ribs Do Men Have?

As previously stated, a man’s rib cage is made up of 12 pairs of rib bones that articulate with the spinal column posteriorly and finish in cartilage anteriorly. The ribs slide across the vertebrae during breathing thanks to the small joints between them.

They enclose and protect the chest cavity, which houses several vital organs like the heart and lungs. In both males and females, there are 12 pairs of ribs (a few individuals have 13 or 11 pairs). The prevalent but inaccurate idea that men have fewer ribs than women stems from the biblical story of Eve being formed from one of Adam’s ribs.

How Many Ribs Do Women Have?

Unless there has been surgical intervention or a serious congenital abnormality, men and women have the same number of ribs. Males and females of any particular species have the same number of ribs. In a human, there are 24 ribs, or 12 pairs.

An extra cervical rib, a single extra rib at the base of the neck, is present in some people. This is extremely rare and can affect either sex (it is estimated that 0.2 percent to 0.5 percent of the population is affected). Some people have only eleven pairs of ribs. However, it can happen to either sex.

Atavism is a situation in which a difference in genetic expression features present in our nonhuman ancestors arises in our bodies, resulting in an additional rib. Atavism is exemplified by the additional ribs.

What Is The Difference Between Male And Female Ribs?

When male and female rib cages are compared, the females’ ribs grow longer in relation to the axial skeleton. Both males and females have the same number of ribs. The male thorax is wider than the female thorax, which is thinner.

Women have far more breast tissue than males, while men have significantly larger chests in terms of circumference and overall depth. The main difference between the male and female rib cages is that the male rib cage is wider and deeper.

Note: The core difference between a man’s and a woman’s ribs

  • Female ribs are longer than male ribs in proportion to their height, resulting in:
  • A female rib cage with more angulation of the ribs
  • Men and women have varied costal cartilage calcification patterns (the non-bony region of the ribs in the front of the chest).

The rib cage, which includes the sternum, is made up of 12 thoracic vertebrae and 24 ribs. The rib cage opens up more with each consecutive rib, starting with the first or highest. The ribs are semi-rigid and expansile, meaning they can expand.

During respiration and other activities, the tiny joints between the ribs and the vertebrae assist in achieving a gliding movement of the ribs in the vertebrae. True ribs are attached to the sternum and the first seven, whereas false ribs are attached to the sternum and the final two are floating ribs.

What Side Is The Missing Rib In A Man?

Accurately pointing out which rib is missing can be quite a stretch. As others have stated, men and women share the same number of ribs. Nevertheless, there is another possibility: the term “rib” is merely a euphemism for another bone. It turns out that men have one fewer bone than women do, termed the baculum.

The penis bone is another name for it. This bone is found in many other mammals, including our closest cousins, the gorilla, and chimpanzee. However, it is noticeably lacking in humans. Of course, only men are missing this bone, not women. And I don’t believe it’s a stretch to believe that this was the inspiration for Genesis’ creation myth.

Our forefathers were not irrational, and they must have seen that whereas many animals have a bone in their penis, humans do not. Given this information, it’s only rational to conclude that if God created men, he must have “taken away” this bone for some reason.


Is it possible to be born with an additional rib?

Both genetic and environmental factors are likely to be involved in most cases. Animal research has looked into the significance of HOX genes in the development of additional ribs. Environmental exposures, such as maternal exposure to foreign toxins or stress during pregnancy, have also been implicated in studies.

Is it true that a woman has more ribs than a man?

No, men and women both have the same number of ribs (it’s a common misconception that women have one fewer). There are 24 ribs in total, divided into two sets of 12. The spine (vertebrae) in the back connects each pair of ribs. Ribs come in three varieties:

Is having an additional rib common?

Each adult has 206 bones, 12 on each side, including 24 ribs. However, one out of every 200 people has an extra rib. The cervical rib is the name given to this rib.

Who is the owner of the extra ribs?

A cervical rib is an additional rib that is present at birth in about 1 in 200 people. Thoracic outlet syndrome affects about one out of every ten patients who have a cervical rib. The thoracic outlet is a tube located directly above the first rib and behind the collarbone (clavicle).

In the human body, how many pairs of ribs are there?

Regardless of gender, the vast majority of people are born with 12 pairs of ribs each, for a total of 24. People born with unique genetic anomalies are an exception to this rule.


The ribs are crucial in the body because they protect organs and help with breathing. The average person is born with 24 ribs, 12 on each side. I thought that our post on “how many ribs do males have” was informative.

Contrary to popular belief, both men and women have the same number of ribs. However, some people are born with more or fewer ribs than the average of 24. A large number of ribs rarely causes health problems.
