How Many Ribs Do Men Have Everything You Need To Know

Are you presuming that the ribs of a male and female primate are identical? This led to the writing of the piece “How many ribs do men have?” The protective cage (chest) of the thorax is made up of a collection of long, flat, curving bones known as the ribs. The 12 pairs of ribs that make up the human rib cage join the spinal column posteriorly and finish as cartilage anteriorly. The ribs may move across the vertebrae during breathing because to the small joints between them. They cover and partially protect the chest cavity, which contains several vital organs including the heart and lungs.

Both men and women have 12 pairs of ribs (a few people have 13 or 11 pairs). The myth that Eve was made from one of Adam’s ribs in the Bible may have contributed to the widespread but false idea that men have fewer ribs than women.

The Ribs Anatomy and How Many Ribs Do Men Have?

The ribs’ anatomical parts are typically:

  • Its shape is wedge-shaped. It features a bone wedge between its two articular surfaces. While the vertebrae above articulate with one facet, the numerically comparable vertebrae articulate with the other.
  • The neck solely connects the head to the body; it does not have any bony prominences. At the junction of the neck and the body, a roughed tubercle with a facet articulates with the transverse process of the corresponding vertebra.
  • The body of the rib, or its shaft, is curved and flat. A groove on the shaft’s interior surfaces shields a group of blood vessels and nerves that feed the thorax from damage.

The most of ribs with these ingredients are common ribs. Ribs that lack these qualities are said to as atypical.

  • The first rib is broad and short, and it has one articular facet and two costal grooves.
  • The serratus anterior muscle is attached to the superior surface of the tuberosity on the long, thin second rib.
  • Tenth rib (only has one articular facet)
  • The 11th and 12th ribs, which have one articular facet without a neck.

Based on how they connect to the sternum, the ribs are split into three groups:

  • True ribs: Their costal cartilages immediately articulate with the sternum from the first to the seventh rib. They are joined to the sternum by the sternocostal joints. The first rib is an exception since it may articulate with the clavicle differently because to the costoclavicular joint.
  • False ribs (8, 9 and 10): The costochondral joint, which joins their costal cartilages to the seventh costal cartilage, allows them to indirectly articulate with the sternum.
  • The floating ribs and the sternum do not articulate (11 and 12). (two ribs away).

Typical and Atypical Rib Structures

The head, neck, and body of a typical rib are:

  • The wedge-shaped head has two articular facets that are divided by a wedge of bone. While the vertebrae above articulate with one facet, the numerically comparable vertebrae articulate with the other.
  • The neck serves just to connect the head to the rest of the body and lacks any bony prominences. Where the neck meets the body, there is a roughed tubercle with a facet for articulation with the corresponding vertebra’s transverse process.
  • The body of the rib, or its shaft, is curved and flat. The thoracic neurovascular supply has a groove on the inner surface of the shaft that shields the veins and nerves from damage.
  • Because they exhibit qualities that aren’t present in all ribs, ribs 1, 2, 10, 11, and 12 are regarded as being “atypical.”
  • The shortest and broadest rib is number 1. It just has one facet on its head for articulation with its matching vertebrae because there isn’t a thoracic vertebra above it. The superior surface has two channels that the subclavian vessels can travel through.
  • The two articular facets on the head are the same on ribs 1 and 2, however rib 2 is shorter and thinner. On its top side, there is an area that is roughened where the serratus anterior muscle begins.
  • Rib 10 only has one facet, which is used to articulate with the vertebrae that are numerically equivalent to it.
  • Ribs 11 and 12 only have one facet for articulation with the vertebrae to which they belong, and they lack necks.

What Role Do The Ribs Play in The Body?

Various tasks are provided by ribs.

  • The mediastinum and thoracic cavity’s contents are shielded.
  • Move superiorly (up), inferiorly (down), anteriorly (front) and posteriorly (back) to ease breathing. The thoracic cavity expands or contracts as the ribs move, aiding the lungs in breathing. The muscles that regulate these movements are the diaphragm, external intercostals, and the intercartilaginous portion of the internal intercostals.
  • giving some muscles a place to attach or their point of origin.
  • During development, while the child is still in the womb, it participates in the process of erythropoiesis, or the creation of red blood cells.

The Rib Ligaments

The costotransverse ligament, which consists of three parts, is the primary ligament that attaches to the ribs. ‘The’ costotransverse ligament is the first part, and it connects the matching transverse process to the rib.

The next pair of fibers, the lateral costotransverse ligament, attaches the transverse process of the spine to the rib immediately distal to the tubercle. The final part is the superior costotransverse ligament, a two-layered ligament with fibers that are orientated at right angles. This joins the transverse process of the vertebra above to the superior border of the rib.

With eleven pairs, the external intercostal muscles are the most superficial in the region. They extend downward from the superior edges of the ribs to the lateral edge of the costal grooves. The fibers of this muscle travel anteroinferior obliquely across the thoracic wall, from the tubercles to the costal cartilages of the ribs. When you inspire, these muscles assist in lifting your ribcage.

Eleven pairs make up the internal intercostal muscles, which are located behind the external intercostals. These extend from the inferior border of the coastal groove to the superior edges of the ribs below. These muscle fibers extend in a posteroanterior orientation before returning to an oblique path. These muscles are only visible from the parasternal region to the angle of the ribs. In order to force expiration, they depress the ribs.

The lateral thoracic wall is where we typically find them, and they go from the medial edge of the costal groove to the medial surface of the rib below. These muscles are distinct because the neurovascular bundles pass through the space between the innermost and internal intercostal muscle layers. These muscles serve to compress the ribs during forced expiration.

How Many Ribs Do Men Have vs Women?

How many ribs men have vs women has garnered considerable curiosity throughout history. It is a common misconception that the number of ribs differs between the two genders, stemming from religious anecdotes surrounding Adam and Eve. However, in reality, both men and women possess twelve pairs of ribs, amounting to twenty-four in total. While there are anatomical variations among individuals that may result in slight deviations or extra cervical (neck) ribs, these occurrences do not differ depending on gender. Understanding this fundamental aspect of human anatomy helps dispel any myths or misperceptions regarding rib counts between men and women.



The ribs are important to the body because they protect internal organs and aid in breathing. The average person has 24 ribs when they are born, 12 on each side of their body. I think you will find our post on “how many ribs do men have” to be extremely beneficial. Contrary to common perception, men and women both have the same number of ribs. Nevertheless, some people are born with more or fewer ribs than the typical 24. Rarely does having an extremely high number of ribs cause any health problems.
