The coracoacromial ligament is attached to the lateral border of the coracoids process and to the medial side of the tip of the acromion process.The margin of the facet on the medial aspect of the acromion gives attachment to the capsule of the acromioclavicular joint.The margin of glenoid cavity gives attachment to the capsule of shoulder joint and to the glenoid labrum.Inferior belly of omohyoid arises from upper border near the suprascapular notch.Rhomboideus major is inserted into the medial border (dorsal aspect) between the root of spine and inferior angle.Rhomboideus minor is inserted into medial border (dorsal aspect) opposite to root of spine.Levator scapulae is inserted along the dorsal aspect of the medial border, from superior angle up to root of spinthe e.Teres major arises from lower 1/3rd of rough strip on the dorsal aspect of lateral border.Teres minor arises from upper 2/3rds of rough strip on the dorsal surface along the lateral border.The long head of triceps arises from infraglenoid tubercle.Pectoralis minor is inserted into the medial borderand superior surface of coracoids process.Coracobrachialis arises from medial part of tip ohe tf coracoids process.The long head of Biceps Brachii arises from supraglenoid tubercle and the short head from the lateral part of the tip of the coracoid process.Serratus anterior is inserted along the medial border of costal surface 1 digitation from the superior angle to the root of spthe ine, 2 digitations to the medial border, 5 digitations to the inferior angle.Trapezius is inserted into the upper border of the crest of the spine and into medial border of the acromion.

Latissimus Dorsi lower fibres originate from inferior angle of scapthe ula.

Deltoid arises from lower border of the crest of spinthe e and from lateral border acromion.

Infraspinatus arises from medial 2/3rds of infraspinous fossa, including lower surface of spinthe e.

Supraspinatus arises from medial 2/3rds of supraspinous fossa including upper surface of the spine.

Subscapularis arises from the medial 2/3rds of the subscapular fossa.

The scapula also articulates with the humerus of the upper arm to form the shoulder joint, or glenohumeral joint, at the glenoid cavity. The scapula articulates with the clavicle through the acromion process, a large projection located superiorly on the scapula forming the acromioclavicular joint. The coracoid process should be anterior and superior. Left–In order to determine if a scapula is right or left, orient it so the glenoid cavity (articulating surface) faces laterally (outward) and the spine is posterior (toward back) and superior (upper). How do you find the side of your scapula? Subclavian groove of clavicle (inferior surface of middle one third of the clavicle) The subclavius is a small triangular muscle, placed between the clavicle and the first rib. Does the Subclavius muscle attach to the scapula?
