Humerus and scapula
After completing this study unit you will be able to:
- Describe the parts, surfaces and landmarks of the humerus and scapula in detail.
- Give a general overview of the glenohumeral (shoulder) joint.
- List and describe the ligaments that hold the humerus and scapula in place.
The humerus is a long bone that comprises the bony framework of the arm, while the scapula is a flat bone of the pectoral girdle. The humerus and scapula articulate with each other to form the glenohumeral (shoulder) joint, which is the most mobile joint of the body. Both bones are held together via several ligaments and muscle tendons.
This video tutorial will help you to learn everything about the anatomy of the humerus and scapula.
Alternatively, you can approach each bone individually with these videos:
