Common USMLE question
Abductors and lateral rotators of the shoulder and their innervations


T = Teres Minor I = Infraspinatous = Lateral rotation of the shoulder
D = Deltoid S = Supraspinatous = Abduct shoulder

Teres minor and deltoid innervated by Axillary nerve
Infraspinotous and Supraspinatous innervated by Suprascapular nerve

Note that this is different from SITS (Rotator Cuff) Muscles which are Supraspinatous, Infraspinatous, Teres minor, and Subscapularis
