How Many Ribs Do Men Have?

A human body has 24 ribs that are 12 pairs of ribs, whether a male or female does not matter.

There are some exceptions where people are born with specific genetic anomaly where they either have too many extra ribs that is more than 24 ribs called supernumerary ribs or too few ribs that is less than 24 ribs called as agenesis ribs.

A study was conducted to get an idea of how many people may have unusual ribs a group of researchers carries a study. The studies on 188 pregnant women with single fetuses. It was revealed that 92% of the unborn had normal ribs whereas 5.3% has fewer ribs and 2.7 has more ribs.

Do Women Have More Ribs?

This Is a question that has confused many of us. But the fact is no matter a human is male or female both have same number of ribs.

Although a study has shown that cervical ribs are very rare in general population yet they are more common in females.

The Structure Of Ribs

Doesn’t matter how many ribs do men have? Or women have? Three is no difference between male or female ribs every human’s ribs are divided into three types as per the connection to the skeleton. The flexible costal cartilage is the reason that allows our ribs to expand and contract when we breathe in and out.

The Structure Of Ribs

  • True Ribs:

The 1st seven ribs are called the true ribs. The Costal Cartilage connects directly to the sternum or the breastbone that is in the middle of the chest in the front body. The thoracic vertebra of the spinal column is attached to these ribs in the back.

  • False Ribs:

The 8 to 10 number of ribs are known as false ribs. These 3 ribs connect to the costal cartilage collectively. These ribs also connect to the thoracic vertebrae in the back body.

  • Floating Ribs:

Rib numbers 11 and 12 are called floating ribs. They only connect to the back body via the thoracic vertebrae of the spinal column.

Causes For Variation In Number Of Ribs

There is various number of causes that are the reason for supernumerary ribs and agenesis ribs. Below are a few mentioned.

  • Cervical Rib

Cervical ribs are due to genetic mutation which results in one or two extra ribs in some people. These extra ribs are between the base neck and collarbone. The extra ribs can be one on each side or only one side. They may be full-formed bones or even they can be tissue fiber strands that have no bone.

These ribs may cause a condition called thoracic outlet syndrome (TOS). It is not that everyone with a cervical rib will develop TOS. It mostly appears in adulthood and it is seen that it affects more in men than women

  • Spondylothoracic Dysplasia

This is an autosomal recessive condition also known as spondylothoracic dysostosis. In this condition, the Babies born have fused ribs and vertebrae with small chest cavities. This results to breathing problems

  • Spondylocostal Dysplasia

This is a rare autosomal recessive disorder. In this condition, there is an abnormal development of the ribs and the spine. In this case, it is possible that in addition to scoliosis and fused a person born with this condition may have ribs missing or fused.

  • Goldenhar Syndrome

(Oculo-Auriculo- Vertebral Spectrum)

This is a very rare condition where it affects the spine, ears, or eyes. The babies with this syndrome may have 1 or 2 partially formed or missing ears. Even it can cause benign eyes growths, underdeveloped jay, or check bone. The ribs may b missing, not completely formed, or missing.

Treatment For Abnormal Ribs

Abnormal ribs do not need any kind of treatment unless and until they cause problems like abnormal growth patterns, pain, or breathing problems.

The deformities can be diagnosed via ultrasound before the baby is born. Or can become apparent if the baby has smaller chest and breathing difficulties.

Missing ribs can sometimes also be corrected by surgery. A device called  Vertical Expandable Prosthetic Titanium Rib that is VEPTR can adjust the size of ribs as a child grows.

Some Spinal problems like scoliosis can be treated with surgery
