Anatomical terminology

The thorax (pl.: thoraces or thoraxes)[1] or chest is a part of the anatomy of mammals and other tetrapod animals located between the neck and the abdomen.[2][3]

In insects, crustaceans, and the extinct trilobites, the thorax is one of the three main divisions of the body, each in turn composed of multiple segments.

The human 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 diseases may affect the chest, and one of the most common symptoms is chest pain.
