Thorax

Thorax is a part of the anatomy of humans and various other animals located between the neck and the abdomen. In humans, it is protected by the thoracic cage, also known as the rib cage, which also supports the shoulder girdle and provides attachments for the muscles of the neck, thorax, upper abdomen, and back.

Structure

The thorax includes the thoracic cavity and the thoracic wall. It contains organs including the heart, lungs, and thymus gland, as well as muscles and various other internal structures. Many vital bodily functions, such as respiration and circulation, are performed within the thorax.

Thoracic cavity

The thoracic cavity is the chamber of the body of vertebrates that is protected by the thoracic wall. The thoracic cavity contains the lungs and the heart, which is located in the mediastinum.

Thoracic wall

The thoracic wall is made up of the rib cage and the diaphragm. The rib cage is made up of 12 pairs of ribs, which are connected to the vertebral column at the back and terminate at the front in the sternum.

Clinical significance

Because it houses vital organs, the thorax is often the focus of diagnosis and treatment in a variety of health conditions. Diseases of the thorax are common and can be life-threatening, including diseases such as pneumonia, lung cancer, and heart disease.
