Pictured above is the rotator cuff. These 4 muscles work together to stabilize the shoulder with any and all movements you do with your arm. If any part of the rotator cuff is overworked or injured, your shoulder will not feel 'right,' and you might have limited function with your arm. Check the health of these muscles regularly and take action early when you find an issue in there.
The muscles are layered, showing how some of the muscles are covered by the others. All of the muscles are see-through so that you can appreciate the location and size of each muscle relative to the others.
