Which feature is a tubercle located beneath the glenoid cavity?

• A. Intercondylar Line
• B. Subcapular Fossa
• C. Infraglenoid Tubercle
• D. Supraspinous Fossa

Answer: (C)

Understanding the shoulder blade anatomy, the glenoid cavity sits as the socket for the humerus. Just beneath that socket on the lateral border of the scapula is the infraglenoid tubercle, a small bump that serves as the attachment for the long head of the triceps brachii. This distinguishes it from nearby features like the supraglenoid tubercle (above the glenoid) and from fossae or distant bony lines that aren’t tubercles. So, the tubercle located beneath the glenoid cavity is the infraglenoid tubercle.
