|
Scapulohumeral rhythm |
The ratio of movement between the glenohumeral and scapulothoracic joints during arm movements. |
|
|
Scapulothroacic joint |
The articulation space between the scapula and the ribs. |

|
Shoulder dislocation |
An injury to the glenohmeral joint in which the head of the humerus is pulled out of the socket |
|
|
Shoulder girdle |
An appendicular bony structure made up of the humerus, scapula, and clavicle bones that moves with the arms. |

|
Spine of the scapula |
A horizontal bony ledge that crosses the upper posterior surface of the scapula and divides the scapula into two areas. |
