Scapular Stabilisers (Group)
Region: Shoulder & Arm Muscles · All shoulder & arm muscles
Scapular Stabilisers (Group) at a glance
| Origin | Skull, spine and ribs (trapezius, rhomboids, levator scapulae, serratus anterior, pectoralis minor) |
|---|---|
| Insertion | Scapula (medial border, spine, acromion, coracoid) |
| Actions | Position and rotate the shoulder blade for every arm movement |
| Nerve supply | Accessory, dorsal scapular, long thoracic and pectoral nerves |
◆ Good to know
Smooth arm elevation needs the scapula to rotate in rhythm with the humerus (scapulohumeral rhythm) — these muscles provide it; their individual pages are listed under Back and Chest.
