Yes, the sternal angle, also known as the angle of Louis, is an important anatomical landmark for locating the second rib. It is found at the junction of the manubrium and the body of the sternum and typically aligns with the second rib. By palpating the sternal angle, clinicians can easily identify the second rib and subsequent ribs, facilitating procedures such as auscultation or the placement of medical devices.
The second pair of ribs or the True ribs
Yes, except that the answer would be an angle whose measure is negative. Such angles are quite useful in trigonometry.
The answer depends on what angle B is and which angle is 108. And since you have not bothered to share that crucial bit of information, I cannot provide a more useful answer.
Such is called an exterior angle. A useful theorem is that an exterior angle is equal to the sum of its non adjacent interior angles.
it marks the position of the second rib
A sternal puncture is typically done at an angle of 45 degrees to avoid injury to underlying structures and to ensure proper access to the bone marrow for aspiration or biopsy in diagnostic procedures.
at the level of the inter-vertebral disc between T4 and T5.
The second pair of ribs or the True ribs
The structures that pass through the sternal angle, also known as the angle of Louis, include the aortic arch, the trachea, the thoracic duct, and the ligamentum arteriosum. This anatomical landmark is important for identifying the level of the second rib and the intervertebral disc between T4 and T5.

The sternal area is around the sternum (breastbone) in the center of the chest.
Horses have 8 sternal ribs and 14 asternal ribs.
The sternal angle and the right atrium are typically used to measure jugular venous pressure by observing the level of jugular venous distention during physical examination. The sternal angle is used as a reference point on the chest for measuring central venous pressure.
The xyphoid process is the inferior sternal bony landmark.
The articulation between the manubrium and the body of the sternum is a cartilaginous joint called the sternal angle, also known as the angle of Louis. It is an important landmark for counting ribs and locating structures in the chest.
This results in intercostal and sternal recession in small children with airway obstruction.
