Structure Of The Rib Cage - How Many Ribs In Human Body - What Is The Sternum

In this video we discuss the structure of the rib cage or thoracic cage. We cover the different bones that make up the rib cage and some of the functions of the rib cage.

Transcript/notes

In your body the framework of the chest is called the thoracic cage, or in common terminology the rib cage. Its design functions to protect vital organs such as your heart, and lungs, and also provides points of attachment for many muscles.

The thoracic or rib cage is comprised of 3 main parts, the sternum, the ribs, and the thoracic vertebrae.

The sternum, also called the breastbone, is located in the middle of your chest and it is composed of 3 parts. The manubrium is the widest part at the top of the bone, the body located in the middle and the xiphoid process at the bottom.

There are a total of 12 ribs and they originate on or between the thoracic vertebrae in the vertebral column, and they wrap around the sides of your body and end in the front of your body. Ribs 1 thru 7 are called true ribs because they individually connect to the sternum by way of cartilaginous extensions called costal cartilages as you can see here in this model.

Ribs 8 thru 12, located at the bottom of the rib cage are called false ribs because they do not directly connect to the sternum from their own costal cartilages. Ribs 8 thru 10 fuse with the costal cartilage of rib 7 and ribs 11 and 12 are called floating ribs because they do not connect with the sternum at all.

The thoracic vertebrae make up the thoracic curvature in the vertebral column as you can see here. Each of the 12 ribs articulate or form a joint with the corresponding vertebra, so for example rib 11 articulates with vertebra T11, and some of the ribs such as rib 9 articulates with T9 and the vertebra above T8.

[brentmacaya]

they are located in the chest cavity surrounded by the rib cage.hey pls answer this

[suckme]

So in other words the easiest answer would have been 24 ribs 12 ribs per damn side I don't need to know how they're attached to my human body I just asked a simple question how many ribs are in a human body total of 24 12 per damn side next time the question is presented that away just come out and state that as a fact proper side two sides 24 damn ribs that easy

5. So let man see from what he is created!

6. He is created from a water gushing forth

7. Proceeding from between the back-bone and the ribs,

8. Verily, (Allah) is Able to bring him back (to life)!
