Institute of Human Anatomy - What Makes the Scapula so Unique
The scapula, commonly known as the shoulder blade, is a unique bone in the human body because it is mostly held in place by muscles rather than ligaments. This is unlike most other bones, which are typically secured by multiple ligamentous attachments. The scapula has only one small ligamentous attachment at the AC joint, with the rest of its stability provided by muscles such as the trapezius, rhomboid major, rhomboid minor, and levator scapula. This muscular attachment allows for a wide range of movements, including elevation, depression, retraction, protraction, and rotation of the scapula. This increased mobility is crucial for performing various movements at other joints, particularly the shoulder joint. However, it is also important to have strong scapular sling muscles to stabilize the scapula and maintain its position during these movements.
Key Points:
- The scapula is primarily held by muscles, not ligaments, allowing for greater mobility.
- Only one small ligamentous attachment exists at the AC joint for the scapula.
- Muscles like the trapezius and rhomboids stabilize the scapula.
