Which statement correctly identifies the deep bursae?

• A. Olecranon and Prepatellar
• B. Superficial Bursae
• C. Infrapatellar and Suprapatellar
• D. Subacromial and Iliopsoas

Answer: (D)

Deep bursae are located deeper in relation to joint structures, sitting between moving tissues to minimize friction during movement. The shoulder’s subacromial bursa lies beneath the acromion and deltoid, cushioning the rotator cuff tendons as the arm moves, which makes it a classic deep bursa of the shoulder. The iliopsoas bursa sits deep in the hip, between the iliopsoas tendon and the hip joint/adjacent bones, reducing friction during hip flexion and other motions. Together, these represent deep bursae across different joints, fitting the concept of deep bursae. Superficial bursae, such as those near the skin in front of the knee or elbow, are not considered deep.
