Definition
The small round muscle is part of the posterior (so-called dorsal) shoulder muscles. It is closely connected to the sub-bone muscle (M. infraspinatus) and is partially covered by the delta-shaped muscle. As part of the rotator cuff, it ensures the stability of the shoulder joint together with the muscles M. infraspinatus, M. subscapularis and M. supraspinatus. The shoulder joint is in fact the joint of the body that has the greatest mobility and at the same time is relatively poorly secured by ligaments.
Approach/origin/innervation
Attachment: Lower facet of the large humerus (Tuberculum majus humeri) Origin: Outer surface of the lateral edge of the shoulder blade (Margo laterlis scapulae) Innervation: N. axillaris, C 5 – 6The muscle is contracted when a weight is applied to the body Therefore, the best way to train the small round muscle is to use it: You will find detailed information under Back Training

The function of the small round muscle consists mainly of adduction (bringing the arm laterally to the body), external rotation and retroversion (stretching the arm behind the body). In addition, the small round muscle and the large round muscle form the boundaries of the medial and lateral axial gaps. Information on all forms of movement can be found here in an overview of forms of movement
History
Base: large bony projection of the upper arm (tuberculum majus of the humerus) Origin: lateral edge of the shoulder blade (Margo lateralis of the scapula) Innervation: axillary nerve (C4-6) from the brachial plexus
