Moving up the arm with our Mnemonic Notes series we're going to look at the rotator cuff muscle group: SITS (Supraspinatus, Infraspinatus, Teres Minor, Subscapularis) #CompleteAnatomy #3D4Medical #Elsevier #CompleteAnatomyMnemonicNotes #MnemonicNotes #MedicalMnemonics #MedicalStudent #MedEd #MedicalEducation #MedicalStudy | Complete Anatomy

Why does the rotator cuff get injured? . To raise your arm, the deltoid muscle needs to engage. It's well-suited for this task, but as it works, it rolls the head of the humerus upward. . In a healthy shoulder, this upward roll is balanced by muscles that insert near the head of the humerus from below, such as the subscapularis and teres minor. . However, if these muscles don't engage properly, the humerus head will roll upward, reducing the space available for the supraspinatus tendon to slide

🔴 subscapularis - follow this movement pattern slowly. This is a nice motor control exercise, going against gravity, for internal rotation. The subscapularis muscle is one of the four rotator cuff muscles. It lies on the inner surface of the shoulder blade. 💪🏻Performing a movement slowly is great for a given joint because it encourages stabilization and control. See your doctor prior to performing exercise. #shoulder #subscapularis #shoulderrotation #internalrotation #feelgoodstretch #shoulde
