Rotator Cuff

rotator cuff -- 2016

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.

Infraspinatus

infraspinatus -- 2016

Pictured above is the infraspinatus. It is one of the rotator cuff muscles, and it rotates your arm away from your chest (toward your back) and lifts your arm away from the side of your torso. (click here for a list of all the muscles)

Supraspinatus

supraspinatus -- 2016

Pictured above is the supraspinatus. It is one of the rotator cuff muscles, and it secures the upper arm bone (humerus) against the shoulder blade (scapula) and raises the arm away from your side.
