Name the Four Rotator Cuff muscles
- Supraspinatous
- Infraspinatous
- Teres Minor
- Subscapularis
“SITS muscles”
Why do Rotator cuff injuries usually result in lack of abduction?
Because the Supraspinatous is the most commonly injured, which is responsible for abduction.
Hyper-abduction of the arm can dislocate the _____ Joint
Glenohumeral, because the humerus ends up pointing down when your arm is up
A flattened shoulder, prominent humeral head, flexed elbow, and internally rotated forearm is the clinical presentation of a _______ dislocation
Glenohumeral
Scapular Retraction brings the scapular _____ from the vertebral column, whereas protraction moves the scapula ____ from the vertebral column
Toward, Away
The two main abductors of the arm are :
- Deltoid
- Supraspinatus
The two main External Rotators of the arm are
- Infraspinatus
- Teres Minor
Two main Upward Rotators of the Scapula
- Trapezius (upper and lower)
- Serratus Anterior
How do the radius and ulna look with supination?

Why do you feel the biceps bulge with your palms facing up?
