which structure is highlighted and indicated by the leader line?

Explanation:

Identify the anatomical region

The image displays a lateral view of a human leg model (left) and a corresponding cadaveric dissection (right). The highlighted region is located on the upper lateral aspect of the thigh, superior to the iliotibial tract.

Analyze the highlighted muscle

The highlighted muscle is situated at the anterolateral aspect of the hip/thigh. It originates from the anterior superior iliac spine (ASIS) and the outer lip of the anterior iliac crest, and inserts into the iliotibial tract (IT band).

Differentiate from adjacent structures

The gluteus medius lies posterior to this muscle, while the rectus femoris lies anteromedially. The highlighted muscle is the tensor fasciae latae, which tenses the fascia lata and assists in abduction and medial rotation of the thigh.

Answer:

Tensor fasciae latae
