What is the location of the angle of Louis?
The sternal angle (of Louis) is the angle between the manubrium and body of the sternum it is located 5 cm inferior to jugular notch at the level of the 2nd costal cartilage; thus, it is a useful landmark for rib counting since the first rib is difficult to feel.
What does the sternal angle indicates?
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.

Where is rib 7 and 8 located?
Ribs 1–7 are classified as true ribs (vertebrosternal ribs). The costal cartilage from each of these ribs attaches directly to the sternum. Ribs 8–12 are called false ribs (vertebrochondral ribs). The costal cartilages from these ribs do not attach directly to the sternum.
What is the smallest obtuse angle?
The largest angle in an obtuse scalene triangle is degrees. The smallest interior angle is the measurement of the largest interior angle.
What is a normal costal angle?
A normal finding. The normal costal angle of any age client is less than 90 degrees. A client with an AP:T ratio of 1: 1 has a barrel chest-the costal angle would be greater than 90 degrees in this situation.
What vertebral level is the sternal angle of Louis?
Sternal Angle Of Louis-. Surface landmark- It is felt 5 cm below the suprasternal notch as a tranverse prominence. It marks the joint between Manubrium and sternum- Manubriosternal joint. It lies at the level of 2nd costal cartilage anteriorly and between T4-5 vertebra posteriorly.
What is the SI unit of angle?
The radian is the SI unit of an angle. It is an SI derived unit. Radians describe the angle subtended by a circular arc with the same length as the radius of the circle. For a full circle, length is 2pi so the angle is 2pi radians.
