Ligaments of Shoulder Girdle

Question 1

Trapezoid (coracoclavicular)

Answer 1

attachment: from coracoid process to trapezoid line of clavicle (ant/inf clavicle)
function: stabilizes AC joint limiting medial displacement, protraction and elevation

Question 2

Conoid (coracoclavicular)

Answer 2

attachments: from coracoid process to conoid tubercle of clavicle (post/inf clavicle)
functions: stabilizes AC joint limiting medial displacement, protraction and elevation

Question 3

Acromioclavicular

Answer 3

attachments: from superior aspect of acromial end of the clavicle to the adjacent acromion (reminds me of a symphysis)
function: stabilizes AC joint

Question 4

Coracoacromial

Answer 4

attachments: from lateral border of coracoid process to acromion adjacent (and inf) to clavicular articulation
function: prevents the superior displacement of the humeral head by forming the coracoacromial arch

Question 5

Coracohumeral

Answer 5

attachments: from base of coracoid process to anterior aspect of greater tubercle
function: reinforces superoanterior aspects of joint capsule

part of GH joint

Question 6

Costoclavicular

Answer 6

attachments: from superior aspect of cartilage of first rib to undersurface of clavicle
function: stabilizes sternoclavicular joint, limiting elevation of the clavicle

Question 7

Superior transverse scapular

Answer 7

attachments: from the base of the coracoid process to the medial edge of the scapular notch
function: closes off the suprascapular notch

Suprascapular n/a relation

Question 8

Glenoid capsule

Answer 8

attachment: from the circumference of glenoid cavity to anatomical neck of the humerus

Question 9

Glenohumeral (3; sup/mid/inf)

Answer 9

attachments: from upper part of medial of glenoid cavity to lesser tubercle and anatomical neck of humerus
function: stabilizes glenohumeral articulation

b/t glenoid capsule and synovial membrane
