The sternal angle is the projection formed by the junction between the manubrium sterni and the body of the sternum.

What is the joint between the manubrium and the sternum?

The manubriosternal articulation is that between the upper part of the sternum and the manubrium. The joint is cartilaginous, with a hollow disc in its centre, and is strengthened by the sternocostal ligaments and longitudinal fibrous bands. About 7° of movement occurs at the joint in association with breathing.

Which structure aligns with the joint between the manubrium and body of the sternum?

Manubriosternal Syndrome The manubrium articulates with the body of the sternum by way of the manubriosternal joint at the angle of Louis. The manubriosternal joint is a fibrocartilaginous joint or synchondrosis, which lacks a true joint cavity.

What is the Sternomanubrial Junction?

The manubriosternal joint, sometimes referred to as the sternomanubrial joint, is the articulation between the upper two parts of the sternum, the manubrium and sternal body. It is at the level of the sternal angle or angle of Louis, which is at the 2nd costal cartilage and the intervertebral disc of T4 and T5 1.

What is connected to the sternum?

The sternum or breast bone is a long flat bone located in the central part of the chest. It connects to the ribs via cartilage and forms the front of the rib cage, thus helping to protect the heart, lungs, and major blood vessels from injury….

What is the area below the sternum called?

The xiphoid process /ˈzaɪfɔɪd/, or xiphisternum or metasternum, is a small cartilaginous process (extension) of the inferior (lower) part of the sternum, which is usually ossified in the adult human. It may also be referred to as the ensiform process.

Where is manubrium found in the body?

The manubrium (Latin for “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.

What is the function of the body of the sternum?

What is the main function of manubrium?

The manubrium is the most superior region of the sternum and articulates with the clavicles or collarbones and the first pair of ribs. The manubrium is the thickest portion of the sternum as it carries the greatest physical load.

Where does the sternal angle lie quizlet?

The sternal angle (angle of Louis) is located where and what is it a landmark for? It is located between the manubrium and the body of the sternum- located at the articulation of the 2nd ribs.

What is the angle of Louis What is another name for this and what is its clinical significance?

sternal angle
The sternal angle (also known as the angle of Louis, angle of Ludovic or manubriosternal junction) is the synarthrotic joint formed by the articulation of the manubrium and the body of the sternum. The sternal angle is a palpable clinical landmark in surface anatomy.

What does the angle at the manubriosternal junction mean?

The angle between the manubrium and the body of the sternum at the manubriosternal junction. Marks the level of the second costal cartilage (rib) for counting ribs or intercostal spaces.

Where is the manubrium located on the sternum?

On the lateral edges of the manubrium, there is a facet (cartilage lined depression in the bone), for articulation with the costal cartilage of the 1st rib, and a demifacet (half-facet) for articulation with part of the costal cartilage of the 2nd rib. Inferiorly, the manubrium articulates with the body of the sternum, forming the sternal angle.

Where is the sternum located in the body?

The sternum (or breastbone) is a flat bone located at the anterior aspect of the thorax. It lies in the midline of the chest and has a ‘T’ shape.

Is the manubrium superior to the xiphoid process?

It articulates with the manubrium superiorly (manubriosternal joint) and the xiphoid process inferiorly (xiphisternal joint). The lateral edges of the body are marked by numerous articular facets (cartilage lined depressions in the bone). These articular facets articulate with the costal cartilages of ribs 3-6.
