The answer to the question of who has less ribs, male or female, is both. There are 24 ribs in the human body, 12 on each side. In most cases, each gender is born with the same number of ribs; however, it is possible for a female to be born with one less rib than a male.
This phenomenon is known as cervical rib, where an extra rib is attached to the neck from the seventh cervical vertebra. This rib (or vertebra) is usually much smaller than the other ribs and does not usually cause any medical issues.
So overall, both genders have the same number of ribs on average, but it is possible for a female to have one less rib than a male.

Why do men have one less rib?
The belief that men have one fewer rib than women has been around for centuries, though it is not actually accurate. According to the book of Genesis in the Bible, God removed one of Adam’s ribs to create Eve, but this is not the scientific explanation for the discrepancy.
Instead, the difference comes down to anatomy and chromosomal makeup. Men and women share the same number of ribs; however, women have a longer thoracic vertebral column, which gives the illusion that they have more ribs.
The difference in a man’s and a woman’s rib structures is because women have a wider pelvis, which necessitates a different arrangement of ribs and vertebrae. Men and women also have different numbers of vertebral discs, which can add to the illusion of men having fewer ribs.
There is also a difference in the composition of the ribs between men and women. A study conducted in 2012 found that females have higher levels of collagen in their ribs, making them stronger than those of males.
This makes women’s ribs more resistant to bending, buckling and fracturing.
Ultimately, the belief that men have one fewer rib than women stems from an erroneous interpretation of the Bible, rather than actual anatomical differences.
How many ribs are there in male and female?
In humans, males and females typically have the same number of ribs. Adults usually have 24 ribs, 12 on each side of the rib cage. Humans have 12 pairs of ribs, going from the top rib (1st rib) to the bottom rib (12th rib).
Each pair of ribs is connected to the spine in the back and the breastbone (sternum) in the front. Two of the ribs are known as “floating ribs” (11th and 12th ribs) because they are not connected to the sternum.
Although the number of ribs is the same in males and females, men typically have larger and broader rib cages than women.
Are women’s ribs higher than men’s?
Yes, in general, women’s ribs are higher than men’s. This is due to the fact that women typically have wider pelvises than men, which means that their ribs tend to sit higher in the body than men’s ribs.
Specifically, a study conducted by the American Journal of Roentgenology found that the average height of the male ribcage is 2-3 cm lower than the average height of the female ribcage. The same study also found that there is a greater angle of curvature in women’s ribs than men’s ribs.
For example, the angle of the lower ribs (10th – 12th) is around 70 degrees in women and around 50-60 degrees in men. Additionally, due to their wider pelvises, women tend to have a greater amount of cartilage tissue around their rib cage which results in increased flexibility.
This increased flexibility can also lead to higher or lower ribs compared to men.
Why do I only have 11 ribs?
Humans typically have a total of twelve pairs of ribs. Eleven pairs are considered “true ribs” and the twelfth pair is called “floating ribs. ” It is believed that the floating ribs may have been originally attached to man’s direct ancestor, the ape, to provide the necessary structure for locomotion on the four limbs.
As humans began to adopt an upright posture and walk on two legs, the need for the extra rib diminished and it eventually deteriorated into the “floating ribs” present today.
In some individuals, anywhere from one to three pairs of ribs may be missing due to normal variation in development, or as a result of a medical condition, such as rib fusion. In these cases, the individual would only have 11 or fewer pairs of ribs.
Why do some women’s ribs stick out?
Some women’s ribs may stick out because of a medical condition, such as an eating disorder, or due to health conditions such as anemia or malnutrition. Women may experience thinning of the chest walls due to extreme weight loss or malnourishment, which can cause the ribs to become more visible.
Additionally, women who are very active may be losing fat from their chest area and showing off their ribs more. Women may also naturally have an increased prominence of their ribs due to age, genetics, and body type.
Finally, women may adopt a clothing style such as corsets, tight dresses, or tight tops that further accentuate their ribs.
What is the difference between male and female ribs?
The main difference between male and female ribs is their size and shape. Male ribs are generally larger, wider and more curved than female ribs. This has to do with the different shapes and sizes of the male and female torso.
Male ribs also tend to be more angular, while female ribs are usually more rounded. The length of the ribs also varies between genders, with male ribs usually being longer and female ribs typically being shorter.
Additionally, female ribs usually have more of a ‘V’ shape compared to the ‘U’ shape of male ribs.
Because of the difference in rib shape and size, the way male and female rib cages fit and protect the organs of the chest varies as well. The female rib cage is believed to be more adaptable when it comes to the movement of the lungs, diaphragm, and other organs.
Male rib cages typically have more stability and rigidity, which may provide more protection in cases of trauma or injury.
What does it mean if a woman has an extra rib?
Having an extra rib is a rare medical condition known as cervical ribs. It is caused by the fusion of an extra rib with the normal seventh cervical vertebra. In most cases, cervical ribs do not cause any symptoms and often go unnoticed until a physical exam or imaging test is completed.
The presence of cervical ribs does not usually affect daily activities and does not require treatment, but it can occasionally cause compression of the surrounding nerves and blood vessels, resulting in pain and/or swelling in the shoulder or arm.
If this is the case, treatment may be necessary to alleviate symptoms and can involve medications, physical therapy, or even surgery to remove the rib.
How many ribs does a woman have on her left side?
A woman typically has 12 pairs of ribs on her left side, the same as on her right side. The ribs form a protective cage around the body, extending from the spine in the back of the thorax, around the sides and then the front.
The first 7 pairs of ribs are connected to the sternum, while the last 5 are considered “floating ribs” because they are not directly connected to the sternum.
Do women’s ribs expand with age?
It is possible for a woman’s ribs to expand with age, although it is not a guaranteed outcome for everyone. The expansion can occur in the cartilage of the ribs, which allows for the rib cage to become larger.
This can happen in adulthood due to a variety of different factors, including hormone changes, lifestyle, or aging itself. It is more likely to occur with an increase in weight or during pregnancy, as the pressure from the extra weight can cause the cartilage to stretch.
While it is possible for some women to experience rib expansion, it is not something to be expected for everyone as each person has different genetics and experience varying levels of wear and tear throughout their life.
How common is a 13th rib?
A 13th rib is an incredibly rare anatomical abnormality. While its exact prevalence is unknown, it is estimated to be found in less than 0. 02% of the population. It is most commonly seen in people with other rare skeletal or rib abnormalities such as cervical ribs, unilateral cervical ribs, or thoracic hyperextension.
The 13th rib usually appears as an extra rib on the right side of the rib cage, however it may occur on either side. It is more commonly seen in females, although the exact cause of this is unknown. Symptoms of a 13th rib may include a visible lump or bulge over the rib cage, neck and shoulder pain, weakness and tingling in the arm, chest tightness, and difficulty breathing.
Treatment typically consists of surgery to correct the abnormality and relieve the associated symptoms.
How many ribs can you live without?
It is possible to live without some of the ribs in your body, however the exact number depends on the individual. Generally speaking, humans have 24 ribs in total, with 12 ribs on each side. Of these, the lower 7 pairs of ribs on each side are considered ‘true ribs’, as they are attached directly to the sternum or breastbone.
The upper 5 pairs of ribs on each side are false ribs, as they attach to the ribs below them and not to the sternum.
Of these, the lowest pair of false ribs on each side are referred to as ‘floating ribs’ and they are not attached to the sternum at all. It is possible to live without these lowest pair of floating ribs without any adverse effects to the body.
In addition, it is sometimes necessary to remove ribs in medical or surgical procedures, such as in the case of chest surgery or to make space for organ transplants.
Generally, the fewer ribs you have, the greater the risk to the body, as ribs play an important role in protecting internal organs. All in all, the exact number of ribs you can live without depends on the individual and situation, but typically the lower pair of floating ribs on each side can be safely removed.
Is it rare to have 11 ribs?
No, having 11 ribs is not rare. Most people have 12 pairs of ribs. However, some people may have 11 pairs because of a condition called rib fusion. Rib fusion is when two or more ribs are fused together, causing a person to have fewer ribs than normal.
It can be present in both sexes and any age group, though it is more common in adults. The most common symptom of rib fusion is progressive mild to severe chest pain. Other symptoms may include restricted chest wall movement, shoulder pain, or the presence of a bony lump or ridge along the chest wall.
Treatment typically involves physical therapy or pain management. In extreme cases, surgery may be necessary.
How common is it to have 11 pairs of ribs?
It is not common to have 11 pairs of ribs. The vast majority of the human population has 12 pairs of ribs, called thoracic ribs, that connect to the sternum in the front of the chest and the vertebrae in the back.
This total of 12 pairs is referred to as thoracic cage or rib cage. Though 11 pairs of ribs are uncommon, some people have one or more extra pairs of ribs in the cervical vertebrae of the neck. These ribs are known as cervical ribs, and they cause no health complications.
However, they can present a variety of other symptoms, such as chest pain, nerve impingements and difficulty breathing. Therefore, it is not considered common to have 11 pairs of ribs.
Can you be born with 11 ribs?
No, it is not possible to be born with 11 ribs. The number of ribs in humans is fixed with 12 pairs, making for a total of 24 ribs. Though the exact origin of why there are 12 pairs is not fully certain, it is believed to be closely related to the fact that human heads have 12 cranial nerves, which lead from the brain to the rest of the body.
Having 12 pairs of ribs provides extra protection for these nerves as they course through the body, while also providing extra protection to vital organs such as the heart and lungs. Additionally, having 12 pairs of ribs helps the chest maintain a symmetrical shape, which is important for efficient respiratory functioning.
Rare cases have been reported in which individuals are born with an extra rib. This is typically due to congenital malformation during fetal development and is known as cervical ribs or cervical rib syndrome.
Cervical ribs typically grow down from the seventh cervical vertebra towards the shoulder; this formation can lead to nerve or blood vessel problems and can cause pain or numbness of the fingers and hands.
In some cases, these extra ribs may be surgically removed depending on their position and the severity of the symptoms.
