The sternum is a long flat bone shaped like a capital 'T' located in the center of the thorax. It connects to the rib bones via cartilage, forming the anterior section of the rib cage with them, and thus helps to protect the lungs, heart and major blood vessels from physical trauma. The sternum is sometimes cut open to gain access to the thoracic contents when performing cardiothoracic surgery. The sternum is an elongated, flattened bone, forming the middle portion of the anterior wall of the thorax. Its upper end supports the clavicles , and its margins articulate with the cartilages of the first seven pairs of ribs. Its top is also connected to the Sternocleidomastoid muscle. It consists of three parts, from above downward: In its natural position, the inclination of the bone is oblique from above, downward and forward


Ligaments join bones and other bones together. It is the fibrous tissue from the connective tissue that holds bones


The clavicle is a bone found in the upper torso of of the human body. It is essential in providing support to the arm and shoulder. The clavicle is easily seen and touched in most people.

A structure that separates two or more adjacent elements of the skeletal system. Depending on the type of joint, such separated elements may or may not move on one another. This article discusses the joints of the human body—particularly their structure but also their ligaments, nerve and blood supply, and nutrition. Although the discussion focuses on human joints, its content is applicable to joints of vertebrates in general and mammals in particular. For information about the disorders and injuries that commonly affect human joints, see joint disease.
