dorsal branch (c) of the subscapular artery bends backwards. 

 Dissection Dissection (fig. 14). The ligaments of the scapula and clavicle 



should be examined. 



of ligaments A strong ligament (coraco-clavicular) ascends from the coracoid 

 of the process to the under-part of the clavicle. On removing the areolar 



tissue it will be seen to consist of two parts, anterior and posterior, 



differing in size, and in the direction of the fibres. 



A capsular ligament, connecting the outer end of the clavicle 



with the acromion, will be shown by taking away the fibres of the 



trapezius and deltoid muscles. 



Another strong band (coraco-acromial) passing transversely 



between the acromion and the coracoid process, and a small 



clavicle, 



and of 

 scapula.

Union of the LIGAMENTS OF THE CLAVICLE AND SCAPULA (fig. 14). The 



scapuia. and outer end of tae clavicle forms a synovial joint with the acromion, 

 and is united to the coracoid process by a strong coraco-clavicular 

 ligament. 



The CORACO-CLAVICULAR LIGAMENT consists of two portions, each 

 having a different direction and designation. 



The posterior piece (*), called conoid from its shape, is fixed by 

 its apex to the posterior and inner part of the coracoid process, 

 and by its base to the tubercle of the clavicle, at the junction of 

 the outer with the middle third of the bone. 



The anterior part ( 2 ) trapezoid ligament, is larger than the conoid
