**Core Concept**
The superior angle of the scapula is a key anatomical landmark used to assess scapular position and movement. It is formed by the junction of the lateral and superior borders of the scapula. Understanding the correct level of the superior angle is essential for evaluating scapular dyskinesis and other shoulder pathologies.

**Why the Correct Answer is Right**
The superior angle of the scapula lies approximately at the level of the T7 vertebra. This level is determined by the scapula's position on the posterior thoracic wall, where it articulates with the 2nd to 7th thoracic vertebrae. The scapula's curvature and the angle formed by its borders are responsible for the variation in the level of the superior angle among individuals.

**Why Each Wrong Option is Incorrect**
**Option A:** This option is incorrect because it does not specify a correct vertebral level, and the scapula's position can vary significantly between individuals.
**Option B:** This option is incorrect because it is too high, as the scapula typically lies below the level of the spinous processes of the 7th cervical vertebra.

**Clinical Pearl / High-Yield Fact**
Remember that the superior angle of the scapula is a dynamic landmark, and its position can change with movement and muscle activation. Clinicians should assess scapular position and movement in the context of the entire shoulder complex.

**Correct Answer: C. T7.**
