Scapulohumeral muscles (shoulder muscles)

The scapulohumeral (shoulder) muscles are a group of muscles that surround the shoulder (glenohumeral) joint. They extend between the clavicle and scapula to the humerus, stabilizing the shoulder while also allowing a wide range of arm movements, including abduction, adduction, flexion, extension, and internal and external rotation.

This group includes the following muscles:

• Deltoid (Read more!)
• Rotator cuff muscles
  • Supraspinatus (Read more!)
  • Infraspinatus (Read more!)
  • Teres minor (Read more!)
  • Subscapularis (Read more!)
• Teres major (Read more!)

All these muscles give the shoulder its characteristic shape. The central bony structure where all the muscles meet is the humerus. Among them, the rotator cuff muscles are the primary stabilizers and supporters of the shoulder joint.
