Study Notes
Anatomical Features of the Scapula
- The hyoid bone is classified as a vestigial bone, as it does not articulate with any other bone in the skeleton.
- The coracobrachialis muscle arises from the coracoid process of the scapula, playing a crucial role in arm movement.
- The supraspinous fossa is located on the posterior surface of the scapula, above the spine, serving as the origin site for the supraspinatus muscle.
- The infraglenoid tubercle is found on the lateral border of the scapula, serving as an attachment point for the long head of the triceps brachii muscle.
- The glenoid cavity is situated on the lateral side of the scapula; however, the largest tuberosity, known as the subscapular fossa, provides the attachment site for the biceps brachii muscle at the coracoid process.
