How Does Your Rotator Cuff Guide Your Shoulder?
The four rotator-cuff muscles connect the shoulder blade to the upper arm and help guide the humeral head against its shallow socket. They act with other muscles and supporting tissues rather than stabilizing the shoulder alone.

What the illustration shows
Posterior right shoulder with deltoid removed. Supraspinatus lies above the scapular spine, infraspinatus below it, and teres minor along the lower lateral region. An anterior inset labels subscapularis. A separate schematic joint closeup labels humeral head and glenoid, with curved movement arrows. Three teaching boxes explain the four-muscle cuff and its contribution alongside other stabilizers. Gold AllHumanBody.com and the exact brand slogan appear at the bottom.
How to interpret this poster
- Fine tendon footprints and surrounding muscle subdivisions are illustrative.
- Curved inset arrows denote movement, not measured compression vectors.
- No injury diagnosis, prevention guarantee or exercise recommendation.
- AI-assisted educational illustration; not physician certification, microscopy, a diagnosis or individualized medical advice.
- Fine annotations need enlargement; the full description provides an accessible text alternative.
- Display the full uncropped illustration; do not trim titles, legends or boundary annotations.
