Chest Bones In A Human Body

By:


The shape and support to the entire body is provided by the skeletal system. Multiple internal organs are safeguarded by hard substances, medically known as bones. Bones contain calcium and are quite hard that provide protection to the delicate organs in the body. Not merely these give proper protection, but bones present correct figure to the human body plus offers power. The main organs like heart and lungs are protected by the chest bones. Chest, the medical name for it is thorax, has got 25 bones. The sternum and the ribs are the two main types of chest bones.

The Sternum

The sternum is T-shaped, an extended and flat bone which is at the midsection of the thorax, on top of the heart and middle chest (mediastinum). It is made up of three main parts. The Manubrium, the gladiolus and the xiphoid process form the three parts of sternum. The sternum is located exactly in between the chest and acts as a supports of both the sets of ribs. As in the enhancement phase of sternum, it is separated in to three sections. These three portions are called sternebra. The sternum is nearly 17 cm in length.

The sternum is connected to all the ribs through cartilage. Sternum shields the most important and fine body organs like heart, lungs and the blood vessels, from any form of exterior or bodily injury. Sternum is nothing but vascular tissues. But, a really thin covering of the bone covers this vascular tissue. The thickest part of sternum is manubrium.

The Ribs

There are 24 ribs in a human body. There are 12 ribs each on either side of the chest. The rib bones make a cage like design and hence termed as ribcage. The ribcage surrounds and protects the entire chest. Even the ribcage protect the vital body organs and important blood vessels in the chest cavity. While inhalation, the rib cage shrinks and increases with the pair of lungs which facilitates to breathe comfortably.

From the twelve ribs, seven are called "true ribs". These are called so, as these ribs are directly attached to sternum. Coastal cartilage is the cartilage that connects the sternum and true ribs together. It offers suppleness to the rib cage and even helps in moving along the ribs. The other 5 ribs are often called false ribs and three ribs from these 5 are attached to sternum by cartilage. The remaining two ribs are not connected to the sternum and thus called as floating ribs. These floating ribs are eleventh and 12th ribs that are also called vertebral ribs.

There is inflammation in the coastal cartilage. These are partly supple. There can be a severe damage to coastal cartilage if you experience trauma in the chest. The scientific name for this severe condition like inflammation is called Costochondritis. It is extremely painful and the symptoms lead to cracked rib, lungs are weakened or perhaps somebody enduring this dilemma can have a major heart stroke. If you feel pain in chest, you need to consult the doctor immediately so as to prevent major problem.
