What is another name for the sternal angle?

The sternal angle, also known as the Angle of Louis, is an important anatomical landmark on the sternum. It is specifically located at the junction between the manubrium and the body of the sternum. This angle corresponds approximately to the level of the second rib and serves as a useful reference point for clinicians when locating key anatomical structures in the thorax, such as the bifurcation of the trachea into the main bronchi. Additionally, it helps demarcate the boundaries of various thoracic regions during physical examinations and surgical procedures.

Understanding the significance of the Angle of Louis is crucial in human anatomy as it provides vital orientation points for navigating the thoracic cavity.
