Scapula is a triangular shoulder girdle bone located in upper thoracic region. Forms glenohumeral and acromioclavicular joints with humerus and clavicle. Serves as attachment site for various shoulder and arm muscles
Diamond-shaped muscle connecting scapula to spinal column. Originates from T2-T5 vertebrae and supraspinous ligament. Inserts on medial border of scapula from spine to inferior angle. Deep to trapezius, inferior to rhomboid minor
The humerus is a long bone that extends from the shoulder to the elbow. It consists of three distinct sections: head, neck, and lower extremity. The head is spherical and articulates with the scapula at the shoulder. The body is cylindrical in the upper portion and prismatic in the lower part
The shoulder consists of three bones: clavicle, scapula, and humerus. The main joint is the glenohumeral joint, which connects the humerus to the scapula. The joint capsule is a soft tissue envelope lined by a synovial membrane. The rotator cuff is a group of four muscles that stabilize the shoulder
Reverse fly targets rear shoulders and upper back muscles. Exercise requires only dumbbells and is suitable for beginners. Improves posture, stability, and strength when performed correctly
Rhomboids are two superficial muscles located in upper back. Consist of rhomboid minor and major muscles. Extend between nuchal ligament and thoracic vertebrae
