where is the thorax located on a human
Thorax The thorax or chest (from the Greek θώραξ thorax "breastplate, cuirass, corslet"[1] via Latin: thorax) is a part of the anatomy of humans and various other animals located between the neck and the abdomen.[2][3] 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 diseases may affect the chest, and one of the most common symptoms is chest pain.
Thoracic vertebrae In vertebrates, thoracic vertebrae compose the middle segment of the vertebral column, between the cervical vertebrae and the lumbar vertebrae.[1] In humans, there are twelve thoracic vertebrae and they are intermediate in size between the cervical and lumbar vertebrae; they increase in size going towards the lumbar vertebrae, with the lower ones being a lot larger than the upper.[citation needed] They are distinguished by the presence of facets on the sides of the bodies for articulation with the heads of the ribs, as well as facets on the transverse processes of all, except the eleventh and twelfth, for articulation with the tubercles of the ribs. By convention, the human thoracic vertebrae are numbered T1â€“T12, with the first one (T1) located closest to the skull and the others going down the spine toward the lumbar region.
