Which term describes the hollow area under the scapular spine?

• A. Intertrochanteric line
• B. Supra-styloid crest
• C. Supraacetabular groove
• D. Infraspinous fossa

Answer: (D)

The hollow area under the scapular spine is the infraspinous fossa. The name itself tells you its location: infra- means below, and spinous (spine) refers to the spine of the scapula, so this fossa sits below that spine on the posterior surface. It’s a shallow concavity that provides space for the infraspinatus muscle. The spine above separates it from the supraspinous fossa, which lies simply above the spine. The other terms point to structures on different bones or aren’t standard scapular landmarks, so they don’t describe the region under the scapular spine.
