Study Notes
Scapula Anatomy
- The coracoid process points towards the anterior (front) side.
- The acromion process has two surfaces: superior and inferior.
- The subscapularis muscle is a type of rotator cuff muscle.
- The supraspinatus muscle arises from the supraspinous fossa.
- The deltoid muscle originates from the lateral third of the clavicle and the acromion process.
- The spine of the scapula divides the dorsal surface of the scapula into the supraspinous and infraspinous fossae.
- The rod-like part of the bone on the costal surface of the scapula, called the ridged anterior border, serves as an attachment site for muscles.
- The spine of the scapula also divides the dorsal surface into a smaller supraspinous fossa and a larger infraspinous fossa.
- The infraglenoid tubercle is located on the lateral surface of the scapula, near the glenoid cavity.
- The levator scapulae muscle covers the superior angle of the scapula.
- The latissimus dorsi muscle covers the inferior angle of the scapula.
- A prominent bony ridge, called the supraglenoid tubercle, is present above the glenoid cavity on the lateral or glenoid angle of the scapula.
