The bony thorax is formed by the sternum, 12 pairs of ribs, and 12 thoracic vertebrae. The bony thorax protects the heart and lungs. Conical in shape, the bony thorax is narrower above than below, more wide than deep, and longer posteriorly than anteriorly.
The chest, properly called the thorax, is the superior part of the trunk located between the neck and abdomen. It consists of several components: Thoracic wall. Several cavities. Neurovasculature and lymphatics. Internal organs. Breasts.
The bones of the thorax can be split into 3 main groups – the ribs, the sternum and the thoracic spine. The rib cage consists of 12 paired bones which function to protect internal thoracic organs whilst also aiding breathing.

The thorax is the upper part of the trunk between the neck and the abdomen, containing the chief organs of the circulatory and respiratory systems, such as the lungs and heart.
The sternum (or breastbone) is a flat bone located at the anterior aspect of the thorax. It lies in the midline of the chest. As part of the bony thoracic wall, the sternum helps protect the internal thoracic viscera - such as the heart, lungs and oesophagus.
The thorax forms from the thoracic wall, its superficial structures (breast, muscles, and skin), and the thoracic cavity. A thorough comprehension of the anatomy and function of the thorax will help identify, differentiate, and treat the plethora of pathology that can occur within the thorax.
The thoracic wall consists of a bony framework held together by twelve thoracic vertebrae posteriorly, giving rise to ribs that encircle the lateral and anterior thoracic cavity. The first nine ribs curve around the lateral thoracic wall and connect to the manubrium and sternum.
Anatomy. Where is the thoracic cavity located? Your thoracic cavity is located in your chest. It’s enclosed by the bones and muscles that make up your chest wall. Your thoracic cavity begins just below your neck and ends at the bottom of your ribcage.
The sternum is the elongated bony structure that anchors the anterior thoracic cage. It consists of three parts: the manubrium, body, and xiphoid process. The manubrium is the wider, superior portion of the sternum.
