What is the costal angle used for?
The costal angle is the angle between the left and right costal margins where they join the sternum. The costal margins somewhat protect the higher abdominal organs, such as the liver. The costal margin may be used for tissue harvesting of cartilage for use elsewhere in the body, such as to treat microtia.
What is the costal angle of the abdomen?
The costal angle is the angle between the left and right costal margins where they join the sternum. The costal margins somewhat protect the higher abdominal organs, such as the liver.
What is the difference between costal margin and costal angle?
The costal margin is the medial margin formed by the cartilages of the seventh to tenth ribs. It attaches to the manubrium and xiphoid process of the sternum. The thoracic diaphragm attaches to the costal margin. The costal angle is the angle between the left and right costal margins where they join the sternum.
What is the costal angle of the sternum?
The costal angle is the angle beneath the the sternum. It is created by the costal cartilage that joins what are called the false ribs, the ones tha6t do not directly attach to the sternum via their own cartilage, but attach directly and indirectly to the cartilage of the 7th rib.
Where is costal angle located?
The costal angle is the angle between the left and right costal margins where they join the sternum.
What does a costal angle of 90 degrees mean?
ANS: a normal finding in a healthy adult. The right and left costal margins form an angle where they meet at the xiphoid process. Usually, this angle is 90 degrees or less. The angle increases when the rib cage is chronically overinflated, as in emphysema.
Where is the costal?
The costal margin is the lower edge of the chest (thorax) formed by the bottom edge of the rib cage. Anterior surface of sternum and costal cartilages.
What is the normal angle of the ribs?
Anatomy. The sternal angle, which varies around 162 degrees in males, marks the approximate level of the 2nd pair of costal cartilages, which attach to the second ribs, and the level of the intervertebral disc between T4 and T5. In clinical applications, the sternal angle can be palpated at the T4 vertebral level.

Why is the sternal angle important?
The sternal angle is an important clinical landmark for identifying many other anatomical points: It marks the point at which the costal cartilages of the second rib articulate with the sternum. This is particularly useful when counting ribs to identify landmarks as rib one is often impalpable.
What is costal arch?
The costal margin (costal arch) is an arch formed by the medial margin of the cartilages of false ribs and one true rib (seventh rib to the tenth rib).
Where is the costal arch?
chestCostal arch or margin refers to the lower edge of the chest formed by the bottom edge of the rib cage. It is formed by the 7th to the 10th rib costal cartilages to create the costal arch. Interchrondal junctions or articulations are joints between costal cartilage forming the costal arch and the lower ribs.
What is the costal margin in anatomy?
Costal margin: The lower edge of the chest (thorax), formed by the bottom edge of the rib cage.
How do you measure rib angle?
With patient in supine, place both thumbs on the angle of the last non-floating rib as it attaches into the sternum. Tips of both thumbs should be heading towards xiphoid process. Check angle between thumbs.
Why is it called the angle of Louis?
1 This anatomic landmark is named after the French surgeon Antoine Louis (1723–1792). Since then, the medical literature has variously described this landmark as the Angle of Louis, Lewis, and Ludwig.
What level is the sternal angle?
It is at the level of the intervertebral disc between thoracic vertebrae 4 and 5. This is the superior extent of the heart as well as the inferior end of the trachea when a person is supine.
