Verified step by step guidance

Understand the anatomy of the scapula: The scapula, or shoulder blade, is a flat triangular bone located in the upper back. It has both anterior (front) and posterior (back) surfaces, each with distinct features.
Identify the anterior surface of the scapula: The anterior surface is the side facing the rib cage. It is smooth and concave to accommodate the muscles that attach to it.
Learn the specific regions of the scapula: The subscapular fossa is a large, smooth depression located on the anterior surface of the scapula. It serves as the attachment site for the subscapularis muscle.
Differentiate the other regions: The spine of the scapula, infraspinous fossa, and supraspinous fossa are all located on the posterior surface of the scapula. The spine is a prominent ridge, while the infraspinous and supraspinous fossae are depressions above and below the spine, respectively.
Conclude that the subscapular fossa is the correct answer because it is the only region located on the anterior surface of the scapula.
