Rotator cuff
Understand what you see.
Compresses and stabilises the humeral head during shoulder motion.
Zoom into the original labels. Practise pointing out each structure, then explain it aloud. Diagrams are teaching references; specimen appearance and slide staining vary.
How to recognise it.
- Tendons surround glenohumeral capsule
- Supraspinatus is superior
- Subscapularis is anterior
Point them out.
Tap a number to open its reference, zoom in and locate the structure. Numbers stay the same across views. This key follows landmarks visible in the reference images.
Think first. Then reveal.
Say your answer aloud before opening the suggested response.
01How do you identify rotator cuff?+
Tendons surround glenohumeral capsule. Supraspinatus is superior. Subscapularis is anterior.
02Which tendon is commonly involved in subacromial impingement?+
Supraspinatus, in relation to the coracoacromial arch and subacromial bursa.
03Is teres major a cuff muscle?+
No. Teres minor belongs to the cuff; teres major acts mainly in adduction and medial rotation.
04What is its main functional or developmental significance?+
Compresses and stabilises the humeral head during shoulder motion. Key structures to recognise: Supraspinatus; Infraspinatus and teres minor; Subscapularis.
