The vertebral level corresponding to the sternal angle is the disk between which vertebrae?

Explanation:
The sternal angle (angle of Louis) sits at the level of the second rib where the manubrium meets the body, and it lines up with the intervertebral disk between the fourth and fifth thoracic vertebrae. This landmark is commonly used to orient the chest: it marks the boundary between the superior and inferior mediastinum and helps locate the bifurcation of the trachea. So the vertebral level corresponding to the sternal angle is the disk between T4 and T5.
