The thorax or chest is a part of the anatomy of humans and various other animals located between the neck and the abdomen. 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.
We created an anatomy atlas of the chest and the mediastinum which is an interactive tool for studying the cross-sectional anatomy of the normal thorax based on an enhanced multidetector computed tomography with helical angiography of the thorax (axial plane). Anatomical structures are visible as interactive labeled images.
The spine in the upper back and abdomen is known as the thoracic spine.It is one of the three major sections of the spinal column.The thoracic spine sits between the cervical spine in the neck and ...
The chest is the area of origin for many of the body’s systems as it houses organs such as the heart, esophagus, trachea, lungs, and thoracic diaphragm. The circulatory system does most of its ...
The thorax is the area of the body situated between the neck and the abdomen. The thorax itself can be split up into various areas that contain important structures. The thorax is bound by bony structures including the 12 pairs of ribs and thoracic vertebrae, whilst also being supported by many ligaments and muscles.
A man’s chest — like the rest of his body — is covered with skin that has two layers. The epidermis is the outermost layer that provides a protective, waterproof seal over the body.
In vertebrates, thoracic vertebrae compose the middle segment of the vertebral column, between the cervical vertebrae and the lumbar vertebrae. 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.
The dominant muscle in the upper chest is the pectoralis major. This large fan-shaped muscle stretches from the armpit up to the collarbone and down across the lower chest region on both sides of ...
The thoracic cage is formed by the 12 pairs of ribs with their costal cartilages and the sternum. The ribs are attached posteriorly to the 12 thoracic vertebrae and most are anchored anteriorly either directly or indirectly to the sternum. The thoracic cage functions to protect the heart and lungs.
