Rotator cuff

Joints & stabilisers

Rotator cuff

STRUCTURE & FUNCTION

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.

01 / IDENTIFICATION

How to recognise it.

  1. Tendons surround glenohumeral capsule
  2. Supraspinatus is superior
  3. Subscapularis is anterior
02 / KEY STRUCTURES

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.

03 / VIVA PRACTICE

Think first. Then reveal.

Say your answer aloud before opening the suggested response.

01How do you identify rotator cuff?
SUGGESTED ANSWER

Tendons surround glenohumeral capsule. Supraspinatus is superior. Subscapularis is anterior.

02Which tendon is commonly involved in subacromial impingement?
SUGGESTED ANSWER

Supraspinatus, in relation to the coracoacromial arch and subacromial bursa.

03Is teres major a cuff muscle?
SUGGESTED ANSWER

No. Teres minor belongs to the cuff; teres major acts mainly in adduction and medial rotation.

04What is its main functional or developmental significance?
SUGGESTED ANSWER

Compresses and stabilises the humeral head during shoulder motion. Key structures to recognise: Supraspinatus; Infraspinatus and teres minor; Subscapularis.
