In mammals, the thorax is the region of the body formed by the sternum, the thoracic vertebrae, and the ribs. It extends from the neck to the diaphragm, and does not include the upper limbs. The heart and the lungs reside in the thoracic cavity, as well as many blood vessels.
Where does thorax begin?
The thorax is the region between the abdomen inferiorly and the root of the neck superiorly. [1][2] It forms from the thoracic wall, its superficial structures (breast, muscles, and skin) and the thoracic cavity.
What forms the thoracic wall?
The thoracic wall consists of a bony framework that is held together by twelve thoracic vertebrae posteriorly which give 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.
