Term
What's the clavicle?
Definition
Doubly curved long bones lying across the superior thorax, has acromial (lateral) and sternal (medial) ends.

*Remember a scapula has 3 borders and 3 angles.
Term
What are the scapulae's major landmarks?
Definition
1. Supraspinous fossa. 2. Infraspinous fossa. 3. Spine. 4. Acromion. (Projects posterior) 5. Coracoid process. (Note: projects anterior.) [image]
