Teres Minor Muscle Anatomy - Bodyworks Prime

Teres minor — small muscle, big role in shoulder stability. Origin: lateral border of the scapula Insertion: inferior facet of the greater tubercle of the humerus Action: external rotation of the arm, assists adduction, helps stabilize the humeral head in the socket To release it, I shorten the muscle first by positioning the arm into external rotation, find my depth and pin it, then have them move into shoulder extension and internal rotation to lengthen and stretch the tissue under pressure.
