The thorax is a division of an animal's body that lies between the head and the abdomen.
In humans, the thorax is the region of the body that extends from the neck to the diaphragm, not including the upper limbs.
In insects and the extinct trilobites, the thorax is one of the three main segments of the creature's body.

The skeletal frame of the thorax is formed by the sternum (breastbone) and ribs in front and the dorsal vertebrae in back.
The chest and abdominal cavities are separated by a muscular structure, the diaphragm.
In insects and other arthropods the thorax is a body division consisting of several segments lying between the head and abdomen, to which are attached legs or other appendages.

In humans, the thorax is another name for chest, the cage of bones and cartilage (a type of tissue) that extends from the bottom of the neck to a muscle known as the diaphragm, which separates it from the belly.
The front of thorax is made up of 12 ribs, the sternum (the flat bone in the middle of the chest), and cartilage that connects the ends of ribs with the sternum.
In insects, the thorax is the middle of the three main sections of the body.

The skeleton of the thorax or chest is a cage that encloses and protects the main organs of respiration and circulation.
The lower opening of the thorax is formed by the twelfth thoracic vertebra in the back, by the eleventh and twelfth ribs on the sides, and by the costal cartilages of the tenth, ninth, eighth, and seventh ribs in the front.
Injuries to the bony structures of the thorax are very serious because of the relationship of the thorax to the spine as a whole and because of the importance of the major respiratory and circulatory organs that the thoracic cavity contains.

A retrospective descriptive analysis of the frequency and type of thorax and lung injuries has been performed, and the results were compared with those from previous earthquake disasters that have been reported.
Chest radiographs, physical examinations, and, in some cases, CT scans of the thorax were used in diagnosing the thorax and lung injuries.
The types of injuries that accompanied the thorax and lung injuries were as follows: extremity injury (bone fracture), eight patients; head trauma with subarachnoid hemorrhage, four patients; abdominal trauma, one patient; vertebral injury, one patient; and pelvis injury, one patient.

 Elastic properties of lung and thorax
The steepness of the slope is an index of the stiffness (elasticity) of the lung.
In this experiment the resting volume of the lung (that at which the transthoracic pressure difference is nil) is nearly 60% of the maximum volume of the lung (total lung capacity, TLC).
At about 35% of the TLC the elastic forces between thorax and lung balance: the thorax is below resting volume and pulls at the lung surface, lowering the pleural pressure sufficiently to inflate the lung to a volume at which elastic recoil balances the pull.

 Age-related changes in elasticity of lung and thorax
The thorax being so pliable is a very useful feature, as it allows easy passage through the birth canal.
These features are responsible for the fact that at elastic equilibrium the volume of the lung are not very different from the the minimum volume of the thorax, which in turn is the main determinant of residual volume (RV).
In the 20-yr old subject both the lung and the thorax are stiffer, and residual volume is now a larger proportion of the TLC.
