Anatomy of the Scapula

These flashcards cover the anatomy of the scapula, focusing on the identification and function of its structures.

What are the main structures of the scapula that need to be identified?

Acromion, Coracoid process, Glenoid cavity, Suprascapular notch, Superior angle, Supraspinous fossa, Infraspinous fossa, Acromioclavicular joint, Subscapular fossa, Medial (vertebral) border, Lateral border, Spine, Inferior angle.

What is the function of the Acromion?

The Acromion is a bony prominence on the scapula that provides an attachment point for muscles and ligaments.

Where is the Glenoid cavity located?

The Glenoid cavity is located on the lateral aspect of the scapula and articulates with the head of the humerus.

What is the significance of the Suprascapular notch?

The Suprascapular notch allows the suprascapular nerve and vessels to pass through.

What is the difference between the Supraspinous fossa and Infraspinous fossa?

The Supraspinous fossa is located above the spine of the scapula, while the Infraspinous fossa is located below the spine.

What do the terms medial (vertebral) border and lateral border refer to in scapula anatomy?

The medial (vertebral) border is the edge of the scapula closest to the spine, while the lateral border is the edge furthest from the spine.

What is the Inferior angle of the scapula?

The Inferior angle is the bottom point of the scapula, where the medial and lateral borders meet.

What is the Acromioclavicular joint?

The Acromioclavicular joint is a joint at the top of the shoulder connecting the acromion of the scapula to the clavicle.
