Ribs : Parts of the body

                                        A to Z 2019

 Ribs (Latin costae) are the long curved bones which form the rib cage, part of the axial 


Ribs are classed as flat bones which usually have a protective role in the body. Humans 

have 24 ribs, in 12 pairs. All are attached at the back to the thoracic vertebrae, and are 

numbered from 1–12 according to the vertebrae they attach to. The first rib is attached 

to thoracic vertebra 1 (T1). At the front of the body most of the ribs are joined by costal 

cartilages to the sternum. 

The ribs connect to the vertebrae with two joints, the costovertabral joints.

The parts of a rib include the head, neck, body (or shaft), tubercle, and angle.

The head of the rib lies next to a vertebra. 

The neck of the rib is a flattened part that extends laterally from the head. The neck is 

about 3 cm long.

A tubercle of rib on the posterior surface of the neck of the rib, has two facets (surfaces) 

one articulating and one non-articulating. 

                                                                  Rib Cage

The first seven sets of ribs, known as "true ribs", are attached to the  sternum  by the  

costal cartilages. The first rib is unique and easier to distinguish than other ribs. It is a 

short, flat, C-shaped bone. The vertebral attachment can be found just below the  

neck at the first thoracic vertebra, and the majority of this bone can be found above the 

level of the  clavicle. Ribs 2 through 7 have a more traditional appearance and become 

longer and less curved as they progress downwards.The following five sets are known as 

"false ribs", three of these sharing a common cartilaginous connection to the sternum, 

while the last two (eleventh and twelfth ribs) are termed floating ribs. They are attached 

to the vertebrae only, and not to the sternum or cartilage coming off of the sternum.

In general, human ribs increase in length from ribs 1 through 7 and decrease in length 

again through rib 12. Along with this change in size, the ribs become progressively 

oblique (slanted) from ribs 1 through 9, then less slanted through rib 12.

The rib cage is separated from the lower abdomen by the thoracic diaphragm

which controls breathing. When the diaphragm contracts, the thoracic cavity is 

expanded, reducing intra-thoracic pressure and drawing air into the lungs. This happens 

through one of two actions (or a mix of the two): when the lower ribs the diaphragm 

connects to are stabilized by muscles and the central tendon is mobile, when the muscle 

contracts the central tendon is drawn down, compressing the cavity underneath and 

expanding the thoracic cavity downward. When the central tendon is stabilized and the 

lower ribs are mobile, a contraction of the diaphragm elevates the ribs, which works in 

conjunction with other muscles to expand the thoracic indent upward. 


A rib fracture is a break in the rib bone. This typically results in chest pain that is worse 

with breathing in. Bruising may occur at the site of the break.When several ribs are 

broken in several places a flail chest  results. Potential complications include a 

pneumothorax, pulmonary contusion, and pneumonia.
Rib fractures usually occur from a direct blows to the chest such as during a motor 

vehicle collusion or from a crush injury. Coughing or metastatic cancer   may also result 

in a broken rib. The middle ribs are most commonly fractured. Fractures of the first or 

second ribs are more likely to be associated with complications.Diagnosis can be made 

based on symptoms and supported by medical imaging. 

Rib fractures can occur with or without direct trauma during recreational activity. 

Cardiopulmonary resuscitation (CPR)  has also been known to cause thoracic injury.

There is no specific treatment for rib fractures, but various supportive measures can be 

taken. In simple rib fractures, pain can lead to reduced movement and cough 

suppression; this can contribute to formation of secondary chest infection

consult your doctor before attempting the yoga posture.

It is believed that God put Adam to sleep and created Eve from his ribs.

  2. It's interesting to see that you're writing a2z on human body parts.

    1. In the beginning I was a bit skeptical about this topic. I wondered if readers would read topic that were taught in school. Am glad that I stuck to my plan. Thanks Tomichan M.

  3. My first introduction to the word ribs was through a rib tickling piece of story in my English class. Even today, I associate the word ribs more with humor and less with the parts of the body. Great post as always

    1. Rib ticklers bring joy and smile on the face. Thanks Sonia C.

  4. Excellent article. Talking of the diaphragm which separates the abdomen and the upper part of the body I have often noticed that if we get stomach aches in the abdomen it is mostly because of a digestive problem. But sometimes the pain is near the diaphragm which accoriding to doctors is because of a different reason which I forget now. Excellent article.

  5. There are some folktales that claim that a dog stole Adam's rib, so Eve was eventually created from some other material, like a monkey's tail...

  6. I broke a rib once and wow, did that ever hurt! Having read this I feel almost guilty that I'm having barbecued ribs for supper tonight!

    My A-Z of Children's Stories

    1. May I join you for the barbecued rib supper, Keith :)
      Aah! Broken ribs can be pretty painful, a friend suffered rib fracture a few days ago!! He is busy applying ice pack and bearing the pain!! Poor guy!

    2. Broken rib is painful and you must have enjoyed your barbecued supper. Thanks Keith for dropping by.

  7. I've also heard rib fractures are really painful. My biggest problem is keeping my ribs straight, the way they're meant to be. All this time on the PC seriously messes up my posture.

  8. I enjoyed the yoga stretch for bruised ribs. Soothing

    1. Thanks for reading and watching the video, Kalpanaa

  9. I did not know that CPR that saves life leads to Thoracic injury!
    RaGa's talks sure are a rib-tickler...he he he... :P

    1. I think the famous Micheal Jackson had his ribs fractured during CPR. THANKS kISLAYA g.

  10. Nice informative post once again dear. Loved the way you described it. Yeah RaGa's talks are for sure rib-ticklers

    1. Rib-ticklers and RaGa go hand-in-hand. thanks suhavijay


please show some love......
