Aeromio-Clavieular Joint, between the acromial end of the- 

 clavicle and the acromion process of the scapula. 



A gliding joint similar in movement and function to the 

 ster no-clavicular joint. The two joints give elasticity and 

 increased movement tct the shoulder girdle. 



Ligaments. A capsule surrounds the joint, which is strength- 

 ened to form superior and inferior ligaments. There is often a 

 meniscus of fibro-cartilage to be found in this joint too, but not 

 invariably. 



Accessory Ligaments: Coraco-clavicular between the acromial 

 end of the clavicle and the coracoid process of the scapula. It 

 is in two parts, viz. 



Conoid a triangular ligament attached by its apex to the 

 upper surface of the coracoid process and by its base to the 

 conoid tubercle of the clavicle. 



Trapezoid a ligament on the outer side of the conoid and 

 attached to the upper surface of the coracoid process and to the 

 oblique line from the conoid tubercle. 



MOVEMENTS OF SHOULDER GIRDLE TAKING PLACE AT STERNO- 

 AND ACROMIO-CLAVICULAR JOINTS.
