1. Identify the bones that make up the shoulder girdle.
2. Given the scapula is shaped somewhat like a triangle
a. What landmark is commonly used to determine the direction the scapula is rotating
b. What direction is the landmark moving if the scapula is rotating upward?
3. Which shoulder girdle motion are most linear?
4. Which shoulder girdle motions are most angular?
5. Describe scapulohumeral rhythm? The movement relationship between the shoulder girdle and the shoulder joint and how is shoulder joint motion affected in the absence of scapulohumeral rhythm?
