The Ribs The ribs are a set of twelve bones which form the protective ‘cage’ of the thorax. They articulate with the vertebral column posteriorly, and terminate anteriorly as cartilage (known as costal cartilage). As part of the bony thorax, the ribs protect the internal thoracic organs. They also have a role in breathing – during chest expansion the ribcage moves to permit lung inflation.

Sternum Pain Parts of Sternum. 1  Upper manubrium: The upper section of the sternum. 2  The middle sternum body (corpus): The sternum body joins different ribs. 3  Xiphoid process: It starts as a section of cartilage.

sternum n. pl. ster·nums or ster·na (-nə). 1. A long flat bone in most vertebrates that is situated along the ventral midline of the thorax and articulates with the ribs. The manubrium of the sternum articulates with the clavicles in humans and certain other vertebrates. Also called breastbone. 2.

Thoracic Vertebrae Ribs are generally inserted between two vertebrae, such that each vertebra contributes to articulating with half of the articular surface. Each vertebra therefore has a pair of superior articular facets that face posteriorly and a pair of inferior articulating facets that face anteriorly (except for T12).

Ribs The ribs partially enclose and protect the chest cavity, where many vital organs (including the heart and the lungs) are located. The rib cage is collectively made up of long, curved individual bones with joint-connections to the spinal vertebrae. At the chest, many rib bones connect to the sternum via costal cartilage, segments of hyaline cartilage that allow the rib cage to expand during respiration. Although fixed into place, these ribs do allow for some outward movement, and this helps stabilize the chest during inhalation and exhalation. The human rib cage is made up of 12 paired rib bones; each are symmetrically paired on a right and left side. Of all 24 ribs, the first seven pairs are often labeled as true..

Sternum (Manubrium, Body, Xiphoid Process) Location and Anatomy The bottom of the manubrium has a small facet which is continuous with a small facet at the top of the sternal body to accommodate the costal cartilage of the second rib. The first to seventh ribs are referred to as true ribs because it has its own costal cartilage which connects it to the sternum.

Sternum It connects to the ribs via cartilage, forming the front of the rib cage, and thus helps to protect the heart, lungs, heart and major blood vessels from injury. The sternum is consists of three regions: the manubrium, the body, and the xiphoid process. The word sternum originates from the Greek στέρνον, meaning chest.he manubrium, (Latin: handle), is the broad upper part of the sternum. It has a quadrangular shape, narrowing from the top, which gives it four borders. The suprasternal notch (jugular notch) is located in the middle at the upper broadest part of the manubrium. This notch can be felt between the two clavicles.

- The other strengthening ligaments are the radiate sternocostal ligaments. In the sternocostal articulations one must keep in mind that the ribs consist of a bone and a cartilage. The joints between the sternum and the ribs are formed by the cartilaginous part of the rib.nly some of the Junctions between the ribs and the sternum are synovial joints which are always present between the sternum and ribs 2-5, but ribs 1, 6 and 7 are joined to the sternum by cartilaginous joints, synchondroses. The sternocostal joints are strengthened by ligaments which continue into the membrana sterni.

- Anteriorly, the costal cartilages of the first ribs attach directly to the manubrium by synchondroses, the second through seventh ribs articulate with the manubrium or body of the sternum by synovial cavities, and the eighth through 10th ribs form a synchondrosis with the seventh costal cartilage.

Sternum The sternum or breastbone is a long flat bone shaped like a necktie located in the center of the chest. It connects to the ribs via cartilage, forming the front of the rib cage, and thus helps to protect the heart, lungs, heart and major blood vessels from injury.he sternum is a long, flat bone, forming the middle portion of the front of the chest. The top of the sternum supports the clavicles (collarbones) and its edges join with the cartilages of the first seven pairs of ribs.

Xiphoid Process Pain It rests at the 10th thoracic vertebra. It is the tiniest and lowest part of the sternum. Unlike the other two parts of the sternum namely manubrium and body, there are costal cartilages and ribs that are attached to the xiphoid process.

- The sternum, also known as the breastbone, is the bone located in the center of the chest where the upper ribs converge.It protects the heart and lungs from injury and helps to stabilize the structure of the ribcage. It is found in most vertebrates — exceptions include fish, snakes, and turtles.urtles are one of the few vertebrates that have no sternum. A sternotomy is a thoracic surgery that cuts through the sternum, and is often necessary for reaching the heart or lungs. The xiphoid process lies at the base of the sternum.

Sternum It lies at the level of T10 vertebra. Costal cartilages nor ribs are attached to it. It is made up of cartilage until it ossifies at the age of 40 and in some cases, they become one with the sternal body in old age. 1  The superior border articulates with the sternal body via xiphisternal joint.

- The skeleton of the thorax includes the sternum, ribs and costal cartilages, and thoracic vertebrae and intervertebral discs (fig. 19-1). The sternum, or breast bone, is a flat bone that, from superior to inferior, consists of three parts: manubrium, body, and xiphoid process (figs. 19-1 and 19-2).

How Many Ribs Are Attached to the Sternum? Technically, the body of the sternum is called the breast bone, located below the manubrium. The xiphoid process is a small, smooth cartilagenous substance that petrifies by the time a person reaches 40 years of age. Humans possess 24 ribs, which come in pairs that are located on each side of the body.

Ribs and Costal Cartilages Ribs: There are 12 pairs of ribs, all of which are attached posteriorly to the respective thoracic vertebrae. The upper 7 pairs are attached to the sternum directly through their costal cartilages. Ribs 8 through 10 are attached indirectly to the sternum through the seventh costal cartilage. Their costal cartilages are also attached with each other at different points.

The Sternum The sternum, together with the ribs, forms the ribcage that helps to protect the heart and the lungs, as well as major blood vessels. Ribs are connected to the sternum by cartilage. The sternum is composed of the following three parts: the manubrim, the gladiolus and the xiphoid process.In adults, the three parts of the sternum are often bone that is fused together.The manubrim is located at the top of the sternum.It has slight movement and is connected to the top two ribs.The gladiolus, also called the body, is located in the middle of the sternum.he sternum, together with the ribs, forms the ribcage that helps to protect the heart and the lungs, as well as major blood vessels.

How many pairs of ribs are there what type of Rib 1 and ribs 10-12 articulate with only one vertebral body, and ribs 11 and 12 do not articulate with a vertebral transverse process. Answer “check your understanding” question 17 on page 180. Define the sternal angle. Which rib articulates with the sternum at this landmark? The sternal angle is the junction between the manubrium and the body of the sternum. Rib 2 articulates here.

6c. The Muscles of the Thorax They extend from the tubercles of the ribs behind, to the cartilages of the ribs in front, where they end in thin membranes, the anterior intercostal membranes, which are continued forward to the sternum. Each arises from the lower border of a rib, and is inserted into the upper border of the rib below. In the two lower spaces they extend to the ends of the cartilages, and in the upper two or three spaces they do not quite reach the ends of the ribs.

Chapter 7 The adult sternum form the anterior midline of the thoracic wall and has 3 components. The manubrium is a broad triangular bone that articulates with the clavicles and the cartilage of the first pair of ribs. The body attaches to the inferior surface of the manubrium and articulates with the cartilage of ribs 2-7.
