Ligaments of the Shoulder Girdle

Attachments of the Coracoclavicular Lig

From coracoid process to inf surface of clavicle.

What are the two parts of the coracoclavicular lig

Conoid part: Vertical and prevents upward displacement.
Trapezoid part: Oblique and resists medial displacement.

(Displacement of the clavicle)

Describe the coracoacromial lig

Attachs from coracoid process to acromion. Forms the coracoacromial arch above the humeral head and prevents superior displacement.

What makes up the Glenohumeral lig

Consists of superior, middle, and inferior bands. Stabilize the anterior joint capsule

Describe the coracohumeral lig

Attaches from base of coracoid process to greater and lesser tubercle. Strengthens the superior glenohumeral joint capsule and supports tendon of long head of biceps.

Describe the transverse humeral lig

Attaches from the greater tubercle to the lesser tubercle of the humerus. Holds the tendon of the long head of biceps in the bicipital groove.

Where do all the glenohumeral ligaments originate from

From the ant margin of the glenoid and glenoid labrum

Instertion of superior glenohumeral ligament

Lesser tubercule of the humerus

Where does the middle glenohumeral ligament insert

Ant aspect of anatomical neck

Where does the inferior aspect of the glenohumeral ligament insert

Inf aspect of anatomical neck of the humerus
